Floating in the air/Glitching inside the walls/"Climbing" on the structures-bug

I'm too lazy to check if there's topic about this but now I'm really getting pissed off with this floating in air bug, and sometimes I glitch inside the walls or my character just "climbs" on top of the structures and I have no way to get down except load the game again. This seems like a day one bug which hasn't still been fixed...like seriously how hard is it to fix a bug this simple? And don't tell me to bind that "ghosting" on my keyboard because that is NOT a real solution....7 years and we still have to deal with this, just wow! Otherwise the game is entertaining but that bug is really eating the fun especially when it happens during the fighting.
