The netcode goes berserk on temporary UDP disruption
My guess is that this happened because I had an one-sided disconnect (i.e. outgoing packets won't send).
This is a known esoteric network problem for me (clearly not router-related, might be ISP...) and it sometimes happens for me on other ports, but Odamex is the only one that did.........this, as the result.

In case you didn't know, UDP are technically unreliable. Bits can be lost during the transfert toward the server (or the other way around).
That said, the problem lies to me more on your end rather than on the port itself.
