Hello! I've had some problems with mods recently and was told, that quark can be causing all that problems.
My chat with "The Abyss: Chapter II" dev about the bug:

ToxeNRald351: Hello!
I'm playing on a server with this mod (The Abyss: Chapter II) and recently ran into a problem: I can't go to sleep. I right-click my bed, but can't get in.
Before that, I had a server crash, when me and my friend go to bed together. After that, I got stuck in the Dream World and my friend couldn't connect to the server. I fixed that by teleporting myself back to the overworld, then reinstalled the mod to a curseforge version.
release: you are supposed to go to the dream dimension for one minute when you sleep, after that you should get teleported back, this has issues with quark that we can't fix, make a bug report on their github, hopefully vazkii will fix it

Here's also a crash report from that day
crash-2021-11-20_23.42.19-server.txt

hopefully vazkii can fix I am having same issue for past few weeks or maybe a month

Hello! Quark's moved to 1.18 now-- unfortunately, this means that (unless your bug is critical and/or game-breaking), we're closing support for issues filed for versions prior to it (e.g. Quark on 1.16).

If your issue still occurs on 1.18, or if your issue happens to be rather critical (e.g. consistently crashing the game with no other mods present), please leave another note or open a new issue. Thanks for your cooperation!
