question with summon/dispel

I got this cool summon ability and it has the aloc ability(locust) because I dont want to be able to control it, however I got a feeling this is the reason I cant dispel it, is there anyway to fix it? I have the unit set as a summonable so dispel should work vs it........

ALoced units are also invulnerable i.e. immune to spells.

anyway to fix that? I tride unhide unit, I read somewhere that when you unhide unit it will for some reason make it vulnerable again, it didnt work though

my solution is to make the palyer deselect it whenever it is selected, but thats not 100% reliable.

I really hope that is true, did you check if it makes the unit targeteable too? (different from vulnerable)
