Detect or avoid the childish mind - technical question

Hi, in the last few sessions we found out, that one of my players modifies the maps of our campaign. I have four five players. When we entered the last Session, someone had modified the whole map largely. Is it able to find out who it was? Or is it able to give the players a specific colour? And if not, might it e able having a premium access? Looking forward for your answers. :)

What type of modifications are you referring to? Is the player also a GM?

Easiest fix for this in general is to have a starting map where the players can draw to their hearts' delight that they are always brought back to after every session (by moving the player flag, of course). This way they at least can't add stuff when you aren't there. On the rest, talk to your players. Behaviour like that should not be ok.

I'm curious what the players were actually able to modify. Normally only the GM or co-GM can make changes to the map/background layer.

Drawings and things. my players do that all the time. "I was here 2 hours early and the GM was not." stuff like that. Or a D&D warrior, killing an orc, drawn like a a 6 year old fingerpaint.

When you end up a session, just put the players back onto a specific page like an intro page or prep page. That way, if you're not here, nothing players do matters and it lets them test things on their own without problems :)

What G. said + um.... ask them not to? :)

If it's drawings I believe the initial color (though they can change the color) matches the player's color. I did this and made one of my GMs angry. Then other people found out and he quit the campaign. It was hilarious but sad.

Hi, thanks for the Hints! I will draw my stuff in the background only and delete all the player crap ;-) Bye
