Cheated items - glitch ?

Hello everyone!

We started a new map with some friends after the 1.0 release, and starting today we had the dreadful message: "Picked up cheated item, achievement progress is temporarily disabled"

At first we thought it came from one player who joined the server with items from another server. We cleaned all the tagged items and went on with our lives.

But we just fought the Elder and... Right in the middle of the fight, I picked up a random piece of wood from a felled tree and for some reason I had the cheated item tag. Now, mind yourself, we were 3 players fighting the boss and none of us has even been on a modded server or used dev commands. The player who brought in the first "cheated items" was not even online!

All the drops from the boss (trophy & crypt key) were tagged as cheated items so we had to get rid of them and start again from scratch.

At this point it feels like the mechanic is just glitched. We cannot undersand why these random pieces of wood were set as "cheated".

Does this happen to anyone else?
