I differentiated according to the category stamp used because the behavior of IA enemies and friends much change I can change the category of glitched / glitchess you simply have to specify the patch and diificulte used on video (sorry for my english)

You're right, I remember reading some patch notes that they updated the AI and paths of NPCs.
Is it really that different from no patch though?

If the glitches work in the newest patch and Tara isn't dumb anymore I see no reason to run the old version.

glitches seem to run on any patch I may not have time to test everything ^^

I played a few levels on the newest patch and didn't notice much difference to be honest. There seems to be a tiny delay after you skip the objectives before you get the end mission screen. The one positive thing which I'm not yet sure about is that flying seems easier to control.
