I'm adding mutliplayer networking to my voxel game.
I wanted to share this bug I ran into that took me a full day of detective work to solve. Reliable UDP was the root cause, because I didn't fully understand that the reason laminar recommends us to send a lot of reliable packets, is because, so packet acknowledgment are sent.

I'm using laminar networking library for rust.
