For my info, did you press R to open the interface when selecting the point of interest?

Seems to be related to sniffer, from the log ``` Suppressed: java.lang.IllegalStateException: Unreferenced key: ResourceKey[minecraft:worldgen/biome / snifferplus:timeless_grotto] ```

Seems to be cross mod issue with betternether, does it also happen without this mod?

Likely one will be specific to a certain biome, you can see the biome in the tool tip when hovering over the ore.

Are these from a specific mod?

And from which mod are the mobs that have the issues?

JER version?

Can you provide a client log? That should have some indication of where it breaks

Can you provide a log file?

Can you share a log file?
