Ghost Enemies In Archwing Interception

[NyxOOX]

Towers will often get captured by the enemy without any enemy units around them. When the wave is finished, a good number of the remaining enemy icons show up in the middle of empty space without any enemies. Eventually these "ghost ships" appear or die spontaneously.

This is a client-host thing, where clients will often kill enemies, but they persist on the host's end, where things are 'official'.

 

Also happens at the end of rounds, meaning the host has to go round clearing out the last few.
