-fixes to way too many textures, models and objects to count, by way too many modders to list. thanks again, everybody!
how to apply (the fix assumes a fresh, clean install of T1/TG):
1) make sure the game is not installed in program files or some other protected windows folder.
2) run the installer, select the mods of your choice (all are highly recommended).
3) run thief.exe (as admin, if you have vista/win7).
-requires VC++2008 and the latest directx9 redistributable (june 2010), make sure to install these two as admin, no matter what OS or updates (you think) you have
-do not set any compatibility modes on the exe, this will break the game
-installing the game to a protected folder (windows, program files etc) may result in strange and broken behaviour (vista/win7)
-reboot your pc when you are done with all the install procedures (vista/win7)
-should you decide to try out some other combination of mods, delete the "MODS" folder and run the installer again.
