I noticed that when I updated my server that I play on with a few friends to the newest build of Quark on curseforge that the bottom half of beds started spreading like grass, as are prismarine, quartz stairs. When I removed the mod to try and remedy the issue and connected to make sure all the beds and stairs were gone I get this error on my client. And if I re-add it to the server it acts like nothing has changed at all.

Internal Exception: java.lang.IllegalStateException: Registry entry for minecraft:blocks Block{quark:rain_detector}, id 1378, doesn't yield a name.

update forge

I'm running the newest build for 1.10.2
12.18.1.2045

I take it i'll need to reset the map then since removing the mod causes the crash?

You can try to edit the id map in level.dat manually with an NBT editor

This looks like your ID map got broken. Not really much I can do here.
