So I tried once again. New download, new install, new account.
I managed to play everything till I got the quest that I had to level up my hero. (Around Level 170)
I disabled everything, closed the game reopened it so it is all back to default (1) and without turning anything on I did the quest...
I thank you for the generic answer!
Neither of those options exist in your mod menu. It's only damage up and I haven't touched anything yet. Fresh install, new account still disconnected after like 4 secs for "Unstable connection".
No my connection is not unstable since the unmodded version...
