Everytime i've fallen through the map it's been while pressing the Spacebar while doing random things such as Skyshard, Using abilities in PVE, etc.. I'ts the spacebar somehow effecting this
I typically jump around while playing and it happened to me twice. Once while I was waiting for a boss and jumped up and down in 1 spot and caused me to fell through.
In the beta, weird things would happen when we jumped & so requests were made to fix the jump animation. I wonder if this has to do with that fix? I've noticed that the most common complaint during beta (after I jump I float quite a way before landing or each jump takes me higher & higher til I am almost flying) is no longer occurring.
I've fallen through while just walking without jumping. Earlier, I hit E to enter the bank in Davon's Watch, the screen went dark for that split second of loading, and when it loaded up I was falling through the world. I never even got to see the inside of the bank. I'm a habitual jumper but I've stopped in an effort to see if that was the problem. Doesn't seem to be, at least not for me
