Just started a Create: Above and Beyond server with my friends and added this mod as one of the addons. The server booted up perfectly fine the first time, but after doing a few invasions, and removing the last one we did, I shut down the server for the night. Upon opening the server today I keep getting the same crash log. Upon removing Pure Suffering it worked fine, and will even work with version 1.2.1B of this mod, but not 1.3.0R. Any suggestions on what to do?

The forge version that comes with the server pack for Above and Beyond is 1.16.5-36.2.20

And no data packs for Pure Suffering are being used.

I have an idea what may be the problem, I just need to know what forge version you are running and if you are using any pure suffering datapacks to be sure.

What is unusual is that it is a vanilla Minecraft method crashing because it's apparently not existing within your modpack. If this is the case, then opening a jigsaw block should also crash your game in a fresh world with the modpack you're using. If it does not crash, then I will have to make my own method to circumvent whatever mod removes that method. If you would be willing to test that, I can confirm if this issue is a mod compatibility problem.

Going into a fresh world and spawning, placing, and opening the jigsaw block did everything it was supposed to on the client. No crash was encountered. I'll test using a jigsaw block on the server tomorrow.

Looking it over, this seems to be a client-server sync issue. Will do some experimenting for a fix. Let me know if the jigsaw crashes on your server.

Jigsaw works on the server. No crashes on my end. I appreciate the help by the way.

I have released a bug fix version 1.3.1R on curseforge, let me know if the error persists with the new version. Always willing to help :)

I'll give it a whirl. Thanks again!
