I've heard of a server where structures where rebuild at every restart. This seems to be caused by an save error. Up to now i can't reproduce it. I need some more cases where this issue occures to reproduce and fix. So please post your debug.log file, your Operating system and some hardware specs.

Here is the provided log of the first reporter:
shrineslog.txt

If someone has any idea how to reproduce or fix, you're welcome

I am closing this issue as I have not received any new reports on this problem and the old problem seems to be fixed. Please create a new issue if this problem occurs again

Seems to be cutted off. Did the structures saved correctly last run? There are no errors thrown, so i can't figure anything out. Also this was made with 1.70, so please send the log of 1.7.1-Beta0.2 again, because i added some more outputs

The link takes you to a truncated view there is a link near the top that you can click to see the full log. The last part of the log shows the fail to save chunk error. It still isn't saving the chunks with the Shrines structures. 1.7.1-Beta0.2 doesn't seem to be available through the mod launcher can you link it I'll manually install if it will help.

also is this block any use since this is a server set up with terraforged world gen?

I'll send the file to you private.

I thought about this block, but the structures does generate, so i don't think this is a problem. I've tried shrines with terraforged too, but everything worked fine.
Also the problems in the block above doesn't appear.

May this is a conflict with other (worldgen) mods. Could you send me a list of worldgen mods that you have installed?

Thanks for reply
