it will desync every turn when used online - Data from host and clients will be different obviously as one or all will be using the cheat menu so the game resyncs everyone back to the host

If it resyncs everyone back to the host, what if the host uses it?

I tried changing the 0 to the 1, as suggested, and I tested it online and the menu doesn't even show up, nor does it have any options in the key bindings. Is there a way to fix this?

so how i can enable the menü online (private lobby)

Anything?

Putting this here in case I forget how to do it again, and so other people can benefit. And I only use it for LAN games vs bots, no idea if it'll work with other ways

Go to the mod folder at /steamapps/workshop/content/289070/1528155583/
Edit CheatMenuPanel.modinfo and edit <SupportsMultiplayer>0</SupportsMultiplayer> to 1
And in /Base/UI/Panels/Cheat_Panel_World_Tracker.lua, under Initialize(), edit the UpdateCheatPanel(true) to false
