When crashing or relogging while in worg form, you will log in as a stag beetle. A message along the lines of "reverting to the standard form" or something similar, appearing.
This happened to the characters Hcaerek and Cedric Davids, hours apart, though the same reset.
This would be the same problem as with custom npc forms being used for a pc, I think.
It is a problem with any and all types of forms from what I have seen except maybe lycanthrope forms.
This bug has transformed. Now, if you relog as a worg, you will lose worg shape and become your base humanoid race. You will retain the bonus HP even though resting, and it will add to the bonus HP of your next wildshape.
Awesome, though exploitable. I don't know whether it is the same with other wildshapes, and in every instance this has happened there has been several hours between log off and log in.
Character is a half-orc druid of Chauntea.
