I played two (and lost) games against a guy who was map hacking. (Watching the replay there is no doubt). For anyone who wants to watch a blatant hacker account is https://aoe4world.com/players/9525657-aoslidjhoi
If you want to watch the replays search my account Eriulf against the player in the link.
Hopefully, the dev will directly impose the strictest bans on cheating players who actually use third-party software.
the problem is the cheat is public, and the method to make it is public too
i would post it in report bugs but it would just add more cheaters to the game
PM a mod, I think they already know about this tho.
which mod, devs too busy to read dms
