WorldGuard Use Flag can open chests?

I want to make a WorldGuard region so that regular players (non-members) can open doors, but cannot open chests. (By default, they can open neither.)

If I only set "use" to allow, they can open both chests and doors, which is weird. If I set "chest-access" to deny, then even members of this region cannot open chests.

I have PEX, but there is not permissions relating to chest access. I also don't have any chest plugins. Is this supposed to happen? Someone please help!

[I'm running Spigot 1.8 with WorldGuard 6.0.0]

 

I am also having that problem.

 

old thread, but if you still need this, here's the simple fix

flags:
use: allow
chest-access: -g nonmembers deny

be sure to type that exactly and it should work!
Here's my source, you may have already seen it but it can be helpful when working with WorldGuard http://wiki.sk89q.com/wiki/WorldGuard/Regions/Flags
