Colossus attracts friendly fire

Colossus: "Mmm, percival. Sucky-sucky!"
T3 bombers: "Percival! Attack!"
Colossus: Screams in pain

I liked colossus more when its claws weren't "fixed".

Can we make tractor-beamed units untargetable and disabled with EMP? Would remove friendly-firing poor colossus dudes and said units would not be firing back (removes the need to end them quickly).

This is an issue. I did not think other units would target the sucked unit. We will troubleshoot and fix.
