I tried this on main branch, specifically commit https://github.com/foxssake/netfox/pull/241/files
sudo tc qdisc add dev lo root netem delay 150ms with 3 players.
The host always sees the clients properly, but the other 2 clients have problems with syncing their transforms.
This bug takes many tries to replicate, on average 5.

Error log doesn't have anything useful, but posting for curiosity (its beceause of the desynced bombs at the end)

Edit: repulse effect also stops working between clients (host is unaffected)
