Could you allow chest interaction in a region that has build none/deny and chest-access allow ?
We're having some issues with that since our lwc protected chests are inside a reagion that we don't want ppl to build in, but still be able to access their chests.

Currently we need to set the build flag to allow for them to be able to access their chests.

as far as we can tell, neither config setting nor chest-access flag does anything.

I would like a chest-flag also.
But as long as it doesn't exist yet, i resolved it the following way:
Put the chest you want to be publicly available in the protected region. Then make the chest public via LWC, make a 1x1 (or 2x1 if large chest) region (which only contains the chest), set it on build allow and do setparend chestregion protectedregion.
Now everyone(!) can open the cest, but don't destroy it (testet on CB #161 with WE 2.15.2 & WG 3.1.2).

Good suggestion for a few chests, but making 100+ seperate regions in order to make one for each chest, in a "bank" area is probably not a great idea. And he does have a chest flag, it just doesn't do anything

Of course it is not a perfect solution. But for a bank you have to make a region for every customer either way, don't you? So no one can access the chest from another player.

the chests are lwc protected to the individual user, so the chest-access toggle or flag that is in the plugin is what we need, but currently normal users are not able to manipulate chests in a non build region no matter what the the chest flag is set to, nor does it work disabling the chest protect in the config silver.

Ah, sorry, I thought the wrong way.
A working chest-protect flag would of course be useful, so +1 from me.
