when playing skylore beta 2.2 https://www.curseforge.com/minecraft/modpacks/aof-presents-skylore/files/4356684 along with polymer and universal graves. when a player dies they will be unable to move.

sometimes breaking their grave after the fact will do a client crash.

We tried to reproduce it, but without success... keeping it as plausible, but not fully confirmed

As there were no instances reported (either here or directly to me). I'm closing this one
