Only one of the chest's in a double chest is protected.

[Blargmode]

I'm running latch-0.4.2-S6.0.0 on spongevanilla-1.11.2-7.0.0-BETA-269

If I lock a double chest only the section I clicked on will be protected. Anyone could still click on the other half and take the items. If I try to lock the second half it says "There is already a lock here".

The other plugins I have is:
LuckPerms
Prism
Nucleous
SleepVote
FastAsyncWorldEdit

Sorry to hear that this is occurring. This has not been an issue before so I'll definitely look into this as soon as possible (probably later tomorrow).

Thanks for report!

Can confirm that this still happens on Block19, even as of 1.12

I don't have much time this week, but I'll try to fix this tomorrow. If not it'll be this weekend.

This was actually a Sponge issue and is fixed in the latest 7.0.0 SpongeForge and the next 7.0.0 build of SpongeVanilla.

So it seems it was not completely fixed for block snapshots but the next build of Latch will have it functional. Cheers.
