I think there is a need for Permissions to have Grouping as an ON/OFF option, and/or option to set a limit to max number of objects that can be grouped, because people group cards together in games like Codenames to troll, since the cards on the board gets grouped into the shuffled deck.
And since games like that are scripted, the game is destroyed and you have to reload a new one since rewinding usually breaks the script.
There should be a native setting to do this without a workshop item, since it's an important feature. Also, having it under Permissions will allow even people new to hosting to have access to it right away.

Please look into it, because trolls in public games are part of the problem of what makes this great game lose its players.
