Mobs disappearing after a while

[QuickRod]

Hello! In this thread, I would like to mention a specific bug that I recently noticed on skyblock dream. Whenever I want to grind heads so that I can rank up, I type in the chat /is top and I usually go to cire700's because I'm usually alone or when I don't feel like going to somebody's island I grind heads on my own. The thing is, that after a while of AFK-ing and gathering heads, the mobs disappear. The moment I noticed that happened I thought that the cause of that problem was my sword so I immediately swapped to my sword that hasn't fire aspect on it. But, to my surprise, the same thing happened and it kept happening over and over again. I don't know what's causing the mobs to disappear but it's overwhelming me since I AFK for 1-2 hours.

Any help is appreciated
