OK so Ive run into a rather large problem, upon completing Old World Blues DLC I've finally realized there are other snow globes to be collected. Well now I'm bummed because I love collecting everything in the game and this is the one piece I cant go back for. Is there any way of getting that snow globe? Ill pay for it if I have too!
FYI its the Sierra Madre snow globe.

No you can't go back so unfortunately for you, you can't get the snowglobe or if you're on pc use console commands( I had this problem too , I'm on ps3)

Unless your on pc theres no way for you to go back fo it.

damn man that svcks, DM is one of my favorite to look at. the only down side is it doesnt have the snow falling in it just like the one in the big empty

edit: im guessing you didnt collect all 21 of the seirra madre cards?

I'm not an expert and haven't tried this so I could be wrong, but if like on the PC version you can deactivate the DLC's, then it could work like mods. If you deactivate a mod and then save after it, I think it I was told it forgets you played the mod (not sure 100% sure). This MIGHT work for you, but it'd end up forcing you to re-do DM.

Well I missed it like twice, but I used console commands to get it. Now it's on my shelf. :3

First character i mist it, but the second time (last week) i was aware...

Yeah I'm on Xbox so I guess I'm screwed. Like I said I WOULD PAY FOR IT.

Well I guess in a way if you want to pay for it you can pay with your time:

Either go back to a previous save before you finished the DM dlc or...
Start a new character.

I guess im going to PAY for this.
