[1.3.0.56] Moment's lag with some stuff spawning

[Defenestar]

Anyone else seeing a spot of lag when specific units are appearing in combat? I notice it mainly with Destroyers appearing in patrol combats. Like, when the first one appears, I can kinda tell it's coming because there's half a second or so of the action stopping while (I assume) the game engine fishes around in a bag for warship parts.
