Parasite=yes vehicles occasionally bugging out

[mevitar]

I noticed that sometimes VehicleTypes with a Parasite=yes weapon tend to bug out and "vanish" from the map, but still be actually present on it. The map snapshot file shows such vehicle on the 0,0 location, and it can still be selected with the Type Select command, but it will be stuck and unable to do anything at all.
This is especially problematic if such vehicle has a build limit, but i saw it happening with regular Terror Drones too.

Don't know what exactly triggers this issue.

This isn't a recent problem, happens with older Ares versions too, but so far i was unable to tell when it started, or whether it happens in vanilla YR.
