Describe the bug

When I use the Universal Graves mod along with Applied Energistics 2 and Simple BC Pipes, the blocks in my world are not displayed correctly. When I start local world there is no such problem. This happens when connecting to the server.

I already created issues in the AE2 mod repository, they answered that the problem could be related to the Universal Graves mod.

When I enter the command "/polymer dev validate_states", I don't see anything changing, as if the command doesn't work. The result of the output of the command "/polymer export-registry", I added to the archive. I also added server and client logs to the archive (just in case).

Please enable devUtils in /config/polymer/server.json on both server and client and run command /polymer dev validate_states and get output here (logs). Also run /polymer export-registry in singleplayer and pn server and send created files (as a zip)

Looks like there is weird gap in blockstates, will check why it happens

Could you test if adding this fixes it? And if not please send server logs!

After installing this mod, the server crashes on startup.

Try this!

Okay, experimented locally with this a bit. This build should fix the issue. Could you confirm that?

I apologize for the delay in answering. Problem solved, thanks for the fix.
