Core protect wipe bug.

[Plexiate]

So I was experimenting with a spigot build last night when almost no players were online and it just so happen that the few that were online had loaded certain chunks within towns.
These chunks, when reverting back to 1.10.2 spigot build due to an issue with plugin compatibility on 1.11 spigot builds, turned out to be completely erased. Signs blank, chests empty.

Although, I still have the logs of items that were put into chests.

Now you may be asking "Why don't you just place back the missing items?"
Well. Well there is a MASSIVE building that one of my highest donators used for storage.

I also can't just place items back because this was also doubled as a shop, so core protect doesn't log the transactions through using Chest Shops.

Now that I have listed essential information, can someone tell me what actions I should take? (All plugins are up to date)

The most obvious way of checking what it could be is to disable all plugins dealing with signs. Then once you have done this add them one by one and see if the problem persists.

It was a one time incident and I know it had to be coreprotect because it's the only chest that deals with this issue.
Btw we use SQLite
