After skyblock being reset and revamped, I expected for there to be quite a few bugs, and I found one today.
I went on my alt account and added my alt account to my island on my main account. I made a chest with a Lockette sign on it with my alt account and now it cannot be opened or broken (By my alt account nor my main account). I asked @TradeOffer for help with this situation and they told me that only Crew or Cypriot could help me with this issue. Since they won't respond to me in-game, then I figured since they both have regular players tagging them off for some odd reason, a staff member could hopefully tag one of them and help me with my issue
