This one is interesting.
Setup:
Single Windows 10 computer with two profiles accessing FOMM (.14.11.12) and running TTW with the same mods. My Profile and a Profile for my daughter using Microsoft's Family Controls, each profile also has it's own Steam account with family sharing enabled.
The Problem:
ttw with no additional mods runs fine in both profiles, I installed some mods and the game works under my profile but not her's. disable several unrelated mods and it runs on her profile again.
Mods:
Nevada Skies
Vurt's
BLIND
Enhanced items
and any additional required mods for those to run.
Behavior:
Game launches but while loading her save crashes. I am have played around with only enabling certain mods and I cannot pin down which specific ones effect it; one time it seems like Nevada skies is the issues but further testing starts to look like Vurt's. I have gone through and reactivated all the mods in FOMM too. I also notice no matter what mods are loaded the text on her title screen is fuzzy, but only the title text; the menu text is fine. The few times I have gotten the game to load has been without Vurt's yet the trees (the full evergreens in FO3) are present but blocky with rainbow colored "skeletons". This almost indicates to me a video issue (AMD 780 mobile chipset in a AIO HP EliteOne 800) yet the game does not have these problems in my profile, infact is runs great and is beautiful running on ultra high; so maybe a user rights issue then?
I have given her full Control on:
the Steam Folder in Programs x86
The Game folder under C:
The folder in Documents under her profile.
I am out of ideas and not sure what else to supply to diag this issue.
