I hope, I say nothing forbitten here:
-Backuping the balance.txt,
-Open your balance.txt
searching for "Spawn_OffsetHigh" and replace the five numbers you find there with 200.
It should look like this:
Spawn_OffsetHigh = {200,200,200,200,200},
-save it and leave
Now every levelcap in every Dificulty should be level 200.
