Hello all, let me go ahead and put it out there that I know next to nothing related to modding. I know how to put them on, and that is the extent of it. To be honest, I don't even know what a mod list order is. I've been using Fallout Mod Manager for uploading them into the game and it never has asked me for ordering. I am probably just being ignorant and not knowing what I am doing. If I could get a bit of help though, I would really appreciate it.
I saw the posts on your LP before, interesting goals/mod setup you're trying to run. Anyways, to your questions.
First, FalloutNV.esm is in fact the game itself. ESM = Elder Scrolls Master (just go with it, this game engine is old old old and has been used for many games), this is the master game file that contains all the dungeons, NPCs, world geography, weapons, creatures, quests, etc. Basically, anything you see or shoot or talk to or loot or whatever while playing the game without any mods loaded, you're looking at content that is contained in that file. Do not ever uncheck that... in fact I don't think you can run without it automatically being loaded. In any case, leave it alone as it's kind of important.
Second you've got 2 zombie mods it appears. I don't know either of them at all, but if they edit similar/same things or add many new spawns into the game you could be having issues. Try running with one mod only and see if that cuts down your crashes. At the very least if you can't live without both mods in your game, change the load order of the two of them so the other loser mod (mod that is overwritten) now "wins" the mod conflict battle. Simplified: just flip the order in FOMM by dragging the one lower so that it's now higher than the other one or vice versa.
Third, I've read many comments that Populated Wasteland causes issues, from corrupted save games to outright crashes such as what you're experiencing. Remove it and see how your crash situation improves or if it doesn't change at all.
To get a list of your mods, open FOMM and at the top click
Load Order -->
Copy to Clipboard. Open a post window in this forum, right click in the text box and hit
Paste.
Finally, some general comments on your load order, and ordering in general. For the most part, "large changes mods" should load first (at the top), things that add many things or are the overhaul type. A World of Pain and Intrusive Invisible Wall Remover would qualify from your list as they affect many things or alter the worldspace at large. Small tweaks or changes to items or game settings generally come later so that they can override any common settings that the larger mods also change. This is all general advice, there's always exceptions and tweaks that need to be made. There's a manager on here called BOSS that claims to simplify mod order issues, perhaps you could try that. I've never seen the need for it myself to be honest but apparently many people use it. :shrug:
Final, final point for you - I run both A World of Pain and the BulletTime mod and almost never crash (never say never with this game engine).
TL;DR --> it's probably Populated Wasteland or one/both of the Zombie mods causing your issues given when it is you're crashing. Transition or on load crashes are usually due to mods that add lots of creatures / NPCs to the gameworld that the engine chokes on at some point. Remove them all, see if your crashes go away and go from there.
