I have a fresh install of fallout 2 with just the restoration patch.
I install Mr.fixit just overwrite the Obj_dude.int no other file.
when i use the game i can use the interface mod but when i'm click on batch the game freeze.
i have not tried on a fresh install without f2 restoration project
(mr.fixit 1.1 eng) (fallout 2 restoration p. 1.2)
i'm french sorry if my english is dificult to read  :-\

thanks for your work :D

Try on fresh install. Either you've installed MrFixit incorrectly, or this mod is incompatible with FO2 Restoration.
