I have this same sort of issue, but cannot retrieve any error messages or anything at this moment (in a hurry to post this
).
If I or anyone else that has connected to my server try to create a character, we get through the character creation process all the way up to the point where you go back to the character selection screen and the character should appear, but it doesn't... a few seconds later, world.exe crashes.
When I check my database, it seems a character is created, but it doesn't appear to have any stats or anything, and when world.exe is booted again, it finds the character and deletes it, due to it being corrupted.
