Ya a legend mate, thx so much!

May i ask if it was a bug or what it was? (no need to explain if it's complex)

In reply to ManatorDE:

Ah yea it worked for abit, but quickly came back sadly.

The bold number changes alot, seems like teleporting around, takeing certain blocks or just using blocks causes this message to get spammed in console:

It seemed to work for abit, but when i began moving stuff around in my inventory or in chests, the console went crazy again. Haven't noticed other actions causing it yet. Here's a cut from the console:
