Or should I uninstall said mod, load and save my game, and reinstall the newer version? Just wanted to know if NMM's updater was safe on it's own. Thanks everyone.

I've not noticed any problems using it so far. If anything it is very handy, cause you don't have to be at the site to know if a mod has updated.

It only works correctly of mod authors package their mods correctly and update the current version numbers on nexus correctly, not all of them do obviously so ymmv.

It does not always reflect updates accurately. I don't trust it with files that aren't in proper BSA Esp/Esm format. I also don't trust it because of what it does when the Skyrim.esm file goes missing. You can see my warning about that in my blog.

I see. So perhaps checking the archive of the manual download first, then if it's packaged properly I just use the NMM to update it through Nexus.

So updating mods through NMM is safe and won't screw up a save game? Is it best to do one at a time per loading of the save game to avoid errors?

Always read the description of the mod when it gets an update. The author will mention if you need a clean save.
I have a few mods for example, that usually require a clean save + StopQuest before updating.

That got fixed in the last update

Nice of you to pass that info on DarkOne.

That's pretty much it. Not every mod requires the same updating method. Some require a clean save, some don't. Mod managers can do the actual updating for you, but it can't do clean saves or whatever upgrading procedures the mod requires for you.

I've used it since launch and have no problems. Remember that all the updater does is check the version and that's often incorrect, so manually checking is still in order. Also, even if you go to Nexus and download a new version via NMM, all it does is add the archive to your mods list. It doesn't install it. You still have to choose whether or not to do that. I have had multiple versions of some mods that had a few updates close together.

I have no idea about any Skyrim.esm disappearing as I never had that happen.

Note that save game corruption is quite possible for any mod with scripting, and not all mod authors know this yet.

I have never used it but I do know that usually anythign over 50 MB starts giving NMM some problems (it starts Omitting things that it should be downloading even when packaged correctly)

As a Crew member of Deadly Dragons we have had this happen quite often with our Armory mod which is 440 MB

A common fix for this though is Download Manually and Add from file.

For some reason its the From Nexus website to NMM that causes this problem not from file to NMM

@Oyaban:
This is news. 50 MB is nothing, and in fact that's why Nexus increased storage for single files. Does Nexus know? Or the NMM author(s)?

I'm not sure I follow what is happening, though. When NMM tells me there is a newer version, I always have to go to Nexus, log in, check manually, and then download the new version (if I choose to, of course). I never have had any option to automatically install or do anything other than download the packaged file(s) for later installation. Same with Wrye Bash, of course, but I have used Bash for years so maybe I'm just used to that system.

Well heres what I see happening.

Deadly Dragons Updates (which it does do regularly)

and then after a few NMM Users Download it we start gettign bug reports and Our First thing we tell them is Make sure the BSA (the large chunk of the 440 MB armory) Is fully downloaded.

Either By Downloading from FIle or Downloading the BSA manually they both fix all of the problems.

This also happened back when scripts were seperate and not BSAed when the scripts folder got over 50MB there woudl be cases of NMM not downloading all of the scripts in said folder.


Everytime its only when You press the Nexus Download via NMM. Also another big thing we Notice that the Download manually and add from file does fix.

When Peopel Download Via Nexus Website anythign over 50MB (its always this 50 MB thing Not sure why) Has a Chance that gets progressively larger of getting to 78% or 90% or some % and then suddently says out of memory cannot complete download.

THough when they download manually and add from file there is absolutely no problems

I'm referring to the option titled "get missing mod info" for updating mods in NMM. When you have a mod in your load order that shows a newer version in NMM, I select that mod and press "get missing mod info" to select the newest version from a list that pops up. Then on the next time I open NMM it updates the mod. Have I been using this function improperly?

Most people From what I know use NMM to see there is an Update then they go onto Nexus and Update from there.

:/ truthfulyl Im not too sure how Updating Directly from NMM works I manage all mods and updates Manually (now reachign upwards of 120 mods Counting the Texture only that arent esp based) so I have different methods to my madness.

but from what i know the problems on using NMM to Update all revolve around one of two things.

Incorrect packing

Mod Size

Im not sure if the secodn one can be fixed (Ie somehow make NMM's Bug out limit set at 500MB as there is very few mods that will ever break that cap)

Ah hah! Now I understand.

The only thing I have ever used the "get missing mod info" for is to try to find the Nexus site info for mods that must be packaged and installed separately (e.g., a mod with multiple options that doesn't include some type of automated installer such as Dimon's body mods, audio file mods, etc.). However, the option never really worked for me so I just ignored it and found it much simpler to check the mods of that nature. "Get missing mod info" always meant (to me) that you are telling NMM to go find the actual mod page on Nexus so that it can track the version even if you had to install the mod manually (such as the examples I listed).

In my case, I simply check the mods available list for newer versions with the yellow triangle/exclamation mark, compare the info with the list (because the info is often wrong), check the mod manually on Nexus, and download if there is actually a newer version (and I want to get it in my list, of course).

Ok, so it sounds like I should do this from now on too. Just to be safe. Thanks everybody! These forums never cease to amaze me after all these years. cheers!
