I lost connection to my own server (just playing with caves active, no dedicated server), while trying to resurrect.
I don't know why it happend, since it worked and works already in the game with same character.

I already resurrected quite often in the same game. But suddenly while resurrecting, before turning into human again, I lost connection.
I started everything again and tried it at the same firepit, but it happend again.
I loaded the game again, and went to another firepit. There it worked without problems.

It was with the character "Medic" from the workshop.

The last log entries are:
[00:07:34]: table: 4FC198E8 Haunt 105417 - firepit HAUNT
[00:07:34]: Could not find anim [idle_loop] in bank [ghost]
[00:07:34]: Stale Component Reference: GUID 100451, scripts/widgets/widget.lua:292
[00:07:36]: [Error] Dedicated server process terminated prematurely.

and the second time:
[00:09:13] table: 36B069C0 Haunt 100038 - firepit HAUNT
[00:09:13]: Stale Component Reference: GUID 100745, scripts/widgets/widget.lua:292
[00:09:15]: [Error] Dedicated server process terminated prematurely.

And the time it worked at another firepit:
[00:12:15]: table: 53D6A4C0 Haunt 104588 - firepit HAUNT
[00:12:15]: Stale Component Reference: GUID 100745, scripts/widgets/widget.lua:292
[00:12:19]: Stale Component Reference: GUID 100745, scripts/widgets/widget.lua:292

So I think this log is not a help at all... :D
But at the firepit were it not worked laid a pan flute directly on the same place were my ghost was. But I can't imagine that this might cause an error..
