Question

I think this mod is impacting my Shulker farm and causing excessive lag due to obscene numbers of entities. I'm not sure why it took a while for the problem to show up though. Using the F3 menu, I could 2000 - 300 of entities near the shulker farm, and got a massive lag spike, but it seemed there were really only 100 - 200 entities in the area. I killed all the shulkers and there were less than 200, 148 if I recall correctly. I'm not sure if this is the issue with the farm or not, but I decided to remove it to see if it was.

I removed the mod from the folder, but the config file is still there, and I saw the log complain about a missing file.

Is there an uninstall button somewhere, or do you just delete the jar file?

Normally it should be just removing the jar file. Just to be sure you can delete the config file.
If this isnt working, can you upload a log file?
