Hello Apologies if this is in the wrong place, and if you've heard it a hundred times before. I've searched the forum as best I could and while I found simialr problems none seem directly related to mine. Using FOMM and FOSE, I installed a small collection of mods (CotW, FWE, MMM) on an updated version of Fallout 3 with DLC. The mods worked perfectly, except when I level up for the first time (whether I skip beginning or not) I can't assign any skill points or do anything. The game doesn't seem to crash rather just bugged or something. I tried different load orders, unchecking different mods, but nothing happened so I unchecked them all, repatched and tried playing it normally. Same problem. I'm therefore unsure whether the issue is with F3 or the effect of the mods which seem to work otherwise. I gave up on NVAMP for new Vegas because of how much mess it caused and was delighted when these mods worked, I'm just anxious to get F3 to work too. Any help is greatly appreciated. Thanks for your time. EDIT: Turns out, it worked after I deactivated Archiveinvalidation invalidated, only now I won't be able to use MMM. Any ideas?
