Perfect! Thanks for clarifying Maddie! I was actually only kicked once, after that I was still able to play with the said mod on without ever being kicked ever since. You're right it could be something from the server which was fixed after a restart. :D
I was recently kicked out by the console with reason like "Invalid or Unapproved use of modifications?" while I was moving my fishes from my inventory to the fish menu/scale.

My suspect was due to the mod...
