What happened?

For some reason when I have items adder installed on my server with the latest of MythicMobs and I'm getting these errors spammed in my console: https://pastebin.com/HbENpDZ3

After some deep research everywhere testing everything I came in conclusion that itemsadder and mythicmobs was the issue. (removed every plugins, cleared every data etc)

It only happens if both of these plugins are together, I tried contacting mythicmobs support but it's the worse support ever (I have mythicmobs premium+ so I should receive the highest support they can give but after 1 week they closed my ticket without giving an answer)

I'm currently in the process of setting an alt server with 0 things installed to see if itemsadder or mythicmobs is sending data somewhere and something in my dedi is blocking it.

Steps to reproduce the issue

Have mythicmobs and have custom mobs
same thing for items adder
Start the server
and the errors are spamming
