Between versions it does its job, with new things there are bugs, to the 1 star review below me, please understand you need to set what mobs NOT to clear. as for warnings you need to set what messages, like me yours are off

The plugin kills mobs indiscriminately and deletes trash without warning players. All optimizations don't work. This is really exaggerated advertising.

== Paper-1.21-130 ==

The optimization plugin really works! I am amazed, this is one of the best plugins for server optimization, and it is also FREE, which makes it even more unique.

This resource is awesome, good for servers which have constant TPS drops. Can you add the source code of the project, I have many enchantments and bug issues that I can make (A GitHub repository)? I cant find anywhere to report a bug. My console keeps getting spammed and I cant read it anymore except:

Also, can you optimize hoppers and elytra optimization by giving trident + riptide and fireworks a cooldown. Overall, this plugin is good to use, just needs the spamming to be fixed.

This is a necessary plugin in small servers, very good at optimizing your server
