Somewhat recently, I was playing prison and I mis-clicked a chest, and as it was not on my plot I thought it'd deny me. But, it didn't have a sign and so for some reason I was able to get into the chest. No I wasn't trusted to the plot either, so this confused me. Yes I did it to a few others, all empty chests but all on different plot. So if this could possibly get a fix to were people only trusted on the plot(again)? (going to be honest, didn't know where to put it via forums Discussion or Suggestions)
Lol. It has always been like this, not a bug. It's the owner's problem if he doesn't lock his chests and gets looted. Support for this to be added once Prison resets.
