All servers I tried were crashing every 5-10 mins and after the third crash, my character was stuck in database. I succeeded successfully twice to log on the server again but every time it crashed again I was locked in database. I think it all started on server DE 1-1 cause I was able to join only that one while he was on. When it crashed again I couldn't enter any server anymore.
And one big thing I noticed is FPS drops on all servers I tried. I had 70-100 FPS on almost maxed out settings on last week build. Today in this build I got 20 - 50 FPS and performance seemed very low.
One minor bug I found is that you could pass through objects in ATC.
I hope this helps. Keep up the good work!
