Mod Version

BiomesOPlenty_1.15.2_10.0.0.299_universal.jar
(also trying to use BiomesOPlenty-1.15.2-10.0.0.345-universal.jar. The error still occurs)

There's nothing that indicates BOP has anything to do with this. I don't even think we use NBT tags for anything that isn't done automatically already by vanilla.

My apologize. Indeed the problem was in another mod. The error disappeared after removing all mods except BiomesOPlenty_1.15.2_10.0.0.299_universal.jar and installing their again.

After the incident i decided to remove the most mods from the server except the minimum necessary ones.

As for the problematic mod, I think it was gravestone_1.15.2_1.17.0.jar, since there were too many entities of this mod in that area.

Thanks for your reply.
