More Glitches on the Ps3

Noticed a few more very frustrating glitches on the Ps3 lately.
1. Getting stuck.
Hydro, I swear at least once a round I get stuck somewhere, and literally can't move, no matter what I try. Nonetheless fun to taunt at enemies till they kill me... But it sucks. It happens less often on dustbowl, particularly on stage 2 cap 2 on the little bridge over the two frontal entrances.
2. Facestabbing
People told me this was actually lag compensation, and that my back was actually turned to the spy when they stabbed. Simply false. In my experience, any time you back away from the spy and he stabs you, it has potential to register as a backstab. Happens all the time. Perfect example: Granary, middle cap, pyro and scout capping the point. Spy runs in undisguised and the scout shoots, misses, backs up, gets backstabbed, while facing the spy. Pyro lights up, backs up a little, spy "backstabs" him. Neither of them ever turned their back to him. This has actually happened when standing still, too. On the ps3, there is never any safe spot to be stabbed by a spy.
3. Sentry Sapping Glitch
A few times a spy has sapped my sentry and I have been unable to remove the sapper. No idea why. I get the image of the sapper outline like I was the spy about the apply the thing, and was unable to wrench it off.
4. More Skywalking
Somebody skywalked on hydro today... fucking noobs. /rant

We have the getting stuck, the facestabbing the unwrenchable sapper and skywalking on the 360 as well..  Do you guys get the one where spies get stuck to you?  Or the one where demos are useless because grenades and stickies just drop  through the floor?  A while back we had games with reduced gravity.. That was actually pretty cool in small doses..

The low gravity glitch sounds fun!

Were you talking to me?

I can only remember seeing you once or twice

Quote:
Its possible to skywalk on every stage of every map

I always thought the un-fixable sap was the sapper equivalent of a crit?
Most the skywalks aren't worth the effort, the granary underground walk is impossible to beat though. Never seen 2fort skywalking.

Believe me, if you can see it, you can get there. (In TF2 PS3)
