We spend time each release to make it harder but its just a matter of time before stuff is cracked again. The only thing that is a 100% reliably fix is to play in a closed community with people you trust. Unfortunately, with the way our engine works we can not really stop something like cheat engine.
However, the frame work of the cheat engine does not work on eu4, so it is fixable.
The attachment is a place holder, as the save is useless to detect the cheat engine as it is technically outside the game. My friends below can confirm its existence. However, I do not want to post it onto the forums. To utilize it, you also have to download cheat engine on. I have acquired this cheat engine and can dm it to a moderator. However, this week, all 3 of our games have ended due to someone using the cheat engine to tag switch and delete armies/navies. Until this week, I had never had a game end due solely to cheating. For example, I have played competitive multiplayer for nearly 5 years. This cheat engine is destroying large parts of competitive multiplayer. Someone has created a cheat engine which allows you to tag switch, ghost in game, disable host auto save, enable/disable coop and hot join, change game rules, etc.
