From what I can tell, the overlay mod recently included in Antique Atlas cannot be disabled, or force to be held, or banned by ModControl by the server.

The only way to achieve this is to remove it from the jar and ship a custom jar.

Or to change the config of the overlay that only allows it to overlay the atlas in hand.

In config/antiqueatlas/AntiqueAtlasOverlay.cfg, there should be an option called "ENABLED". Setting this to false should disable the minimap. If that's not working, you can set the width to 0 as a temporary workaround.

If that doesn't work, I may be misunderstanding the problem. What exactly is happening, and what exactly to you expect to happen?

Oh wait, I think I see what you're saying...

You want the server to disable the overlay, and the clients to abide by the server's rule.

So this can be fixed with config sync, I guess.

I was slightly confused when I wrote this because the modId changed on the overlay and ModControl was complaining and I assumed it was because the overlay mod just got added.

But, mainly I'd like to force that you must be holding the atlas in one of your hands to render the overlay.

That's the idea, but it should also be an option to defer to client settings.

Its not really that big of a deal.

So you want clients to have the behavior of B:REQUIRES_HOLD=true when on the server, regardless of their local config.
