Tur Julan bonelord judge (in "Tur Julan, Crossing of Wings: Hall of Judgement" cell) forcegreets you two times:

1. if ( player->getpos y > 3450 ) -- warns you and asks you to leave
2. if ( player->getpos y > 3500 ) -- attacks you

If you have high enough speed (I had 300 (base 100 + boots of blinding speed 200, for example)) and you approach him, your character doesn't have enough time to stop between these two forcegreetings, so he forcegreets you the second time immediately. To fix that, the distance between these two points should be increased. In my fix, 3500 value was changed to 3650.
