A player and I were both looking at the Nature's Compass, trying to get the search function to work, when the server encountered this crash:

crash-2019-04-16_23.37.29-server.txt

Please let me know if I can provide any more info.

Wait, I think I figured it out. I must have clicked on the top biome in the screenshot.

Looks like a duplicate of #22 and #20. If you're still experiencing this issue can you try using this beta version instead, replicate the issue under the same conditions, and let me know what happens?

I somehow missed this response, my sincere apologies! I saw in the other issue that the person reported the crash was fixed with the beta file. Would you still like me to test it out and get back to you?
