Chunks not arriving to client

[UnixTMDev]

Over LAN, both systems are running Linux, one Mint, one Debian.
Mint (client) has chunks not being rendered, and some also can't be interacted with, as if they weren't sent at all.
Current mod list:

Feel free to close my issue if this is the wrong place for the issue. Here is a screenshot of gameplay, where the current chunk is not sent at all, and the one being stared at just isn't rendering.
The console just repeats:

on the client, where 12345 is always a (seemingly, idk) random number
Also, the F3 menu says "Waiting for chunk..."

[UnixTMDev]

Fixed, some Fabric-exclusive mods that haven't ported to Quilt sort of 'push' block IDs around, causing all modded blocks to not look like what they are, and chunks with those broken blocks NEVER get sent to any clients. I'll leave this open, seeing as it's still a big issue.
