It doesn't seem to bury big bones and it also got stuck while at hobogoblins (next to crafting guild) while trying to walk to falador bank. It walked east of the sheep farm and just got stuck.
Edit.
Save dialog also doesn't work.
Sometimes it just freezes while fighting (Hill giants, egdville dungeon, bank no foot until inventory is full, melee, bury bones, looting)
P.S. Looking really good though, can't wait for the release on SDN!
