Bug Details: 

Following his restat and rename, trying to enter Falke's burrow causes an immediate disconnect/"Lost connection to server." Relogging onto the character shows him in a pitch-black void. He can still move and talk when in said void but the controls are, strangely, inverted. 

When using the ladder icon to log back onto the character, he spawns in the burrow normally and the controls are not inverted. Interestingly, this only seems to happen when his burrow is entered when it's already locked, and doesn't occur when the burrow is unlocked. It also doesn't send him to the mystery void when locking his burrow from inside.

Most likely a server restart resynced the name on the burrow file with his name in the database.
