Hackers have been running around doing silly stuff ruining the game , ruining esports hoi4 tourneys and genuinely killed hoi4 vanilla mp. We must have an answer from the paradoxians themselves to fix this issue with some form of an anti-cheat.
The anti-cheat will save HOI4 MP from certain doom, Its no wonder that most players play SP and not MP, they don't want to be in the toxic hacker environment that is currently HOI4 MP.
Update , CEO of paradox said they wont , as well the head of HOI4. SO RIP , guess I will come back in 8 months with another update that might be a bomb shell
