Invisible buildings visible in fog. lolwut

[doom_sheep]

long story short, i have a building that has locust and permanent invisibility abilites. the invisibility is removed temporarily under certain conditions but that's probably not important as the problem begins before those.

while you have sight of the building it remains invisible but when your units move away you can see it through fog like any building. any easy way to fix this?

Since it has locust, it means you cannot select or actually do anything with it, right?
Then does it have to be a building? ^^
