Good video Jekkar! And yes, well chosen background music.
This bug is caused by those dark boxes that are used to create darker atmosphere, there\'s one at the way to the new part of Hydlaa (that black blinking box, yes) the solution to get back your head (at least your char\'s one) is to reenter the tavern again, that is, cross again the fronteer between the darkbox and the \"normal world\".
Perhaps those darkboxes are like blackholes and your head appeared somewhere else in Yliakum!
