[SirVer (sirver)]

Looks like something put something else but a GameLogicCommand in the queue which seems weird.

[GunChleoc (gunchleoc)]

Are you still getting this?

[Nasenbaer (nasenbaer)]

TiborB, can you reproduce this bug somehow? Any save game that triggers this problem?

[TiborB (tiborb95)]

No, I have not got it for long time, so it is very rare and not reproducible...

[GunChleoc (gunchleoc)]

Let's close it for now then and assume that our ASan hunting fixed it.
