Alright. The day before I submitted this issue, I had ran into a chunk ban glitch on a server. I do not run the server, it was hosted on Aternos, so I can not get the log files themselves, but I can send a screenshot of the console when it happened because it's a private modded server and I was talking with the person who starts and stops the server and they sent me the screenshot of the console. I will also provide a join error screen since I have that as well.

The way it happened was that the server had a private modpack consisting of other mods along with Quark and the Travelers Backpack mod for minecraft 1.16.5 I was in a mineshaft when it happened. What I had done was that I had placed the bag down so I can pull the sleeping bag out so that the world could skip to day. The bag was under one of the stone dripstone things, I don't exactly remember what they're called. The backpack was relatively full with random items, but had almost 2 stacks of iron, almost a stack of gold, and a couple more items along with both the water and lava tanks were filled. I right clicked the bag and that's what initiated the chunk ban.
