Anyone else crashing when going to Angel Lyceum?
I think I've found the problem and the fix.
I was running the game using the multi client executable and the game couldn't update itself whenever there was a maintenance. I think maybe because game files are added to the maps and whenever someone or a change will appear the game crashes? I'm not sure.
Run Angels Online normally and then after it updates you can use the multi client exe again. Then, entering anywhere with a multi client exe launched game wont have the crash anymore.
