Doom 3 bugs

[opij]

I am getting lots of bugs in Doom 3 (idk which version is it just that it is not version 1.3) they are me suddenly walking in the direction i am facing,not being able to move, games not saving, mods working one time then next run not working,when i am stuck it dosent save. Is there any way to fix. I have 2 mods installed (if that even helps it was happening before i installed the mods)
