I have been added to the same skyblock island for a very long time now, and it usually works. Occasionally I experience a lot of lag in placing blocks and opening chests, but it always works. I logged onto my island today and found that I couldn't access chests, or build on my island. I assumed it was because of lag, caused by the poor Wi-Fi connection in my room. However, after many re-logs, I STILL couldn't place or break blocks, or open chests. I could use chat and see the animals moving, so it wasn't lag. I also noticed that someone else reported the same issue earlier in this forum. I typed "/is info" and it said I had to be on MY ISLAND to access that command, however when I did "/is h" I came back to my island's spawn, as per usual. I tried "/is party" and the two other people in the party were those unheard of. It really is quite unusual. If it could please be resolved A.S.A.P, I would like to be able to use my island. If video evidence is needed, I am happy to oblige.
