I know you don't have it listed as 1.19 but I was using this on 1.19.2 with very rare issues. I can't seem to run the Creeper heal command any more on 1.19.4. Would you know why?

I know it's old. It saved my server when it turned out to work on 1.19.2. Still works just can't use the commands.
I just found Creeperheal2 but it does not let me avoid certain blocks like yours did. I need to make sure chests and barrels etc actually drop items.
Sucks because it's so hard to find a regen plugin that fits my exact need. Thank you for the response.

Man, I wrote this plugin 15 years ago :D

I don't maintain it anymore, but if you have an error in the logs I can try to guess what happened.
