So erm, i am probably dumb, but i tried to change my worlds.txt to make almost perspectives render.
So this is what i put there:

And here is the error, or rather the no error i am getting:

Can anyone tell what I am doing wrong, 'cause at this point I have no idea how to fix my config whilst keeping all the perspectives. But I'm probably just missing something obvious.. Thanks a lot in advance

Okay I'm sorry, I just realized this belongs on the reddit. My apoliges

So tried running my worlds.txt through https://codebeautify.org/yaml-validator and it throws me a:
Error : Indentation problem.
Line : 70 - class: org.dynmap.hdmap.HDMap

Heres my full worlds.txt:
worlds.txt

I tried googling for Identation Problem, but it only brings up threads concerning tabs not being allowed in yaml, but i already removed all of them using Notepad++...
Other than that, as far as my .0000000001% yaml knowledge goes, my identation seems to be fine, but there must be something I'm missing.
