I just read your answer to my comment @dubCUT, but I didn't want to spam the comments again so I opened this topic.
Hopefully this will help you out a bit pointing the cause.

The crashlog can be seen [link removed].

I'm running a 3-server-cluster with island, center and volcano.

793605978 - Super spyglass,
722428442 - Upgraded preserving bin

Everything runs fine now on every server without your torches for the moment.

As a side note:
From april 7th on I noticed that autotorches generated a structure blocking range. You couldn't place any structure around a ~2-3 foundation range where an autotorch was placed.
Never had this before.

I hope this few informations may help.


Cheers!
