Firestorm / Primed Firestorm not working with Proboscis Cernos tentacle field

[Tiltskillet]

While Proboscis Cernos radial explosion is affected by radius mods, the tentacle pull-in effect is not AFAICT.    I tested by duplicating groups of enemies in the Simulacrum, and firing at the same spot in the floor.  There was no difference at all in which targets were pulled in whether I modded with Firestorm, Primed Firestorm, or no +radius mod.

FWIW, Ferrox altfire that has a similar vortex effect isn't affected by the radius mods either. 

It would be really nice to get both of these fixed.

Same goes for the Lenz. It doesn't effect the initial chilling area, but does increase the explosion.

I think this is intended. After all, the mod description says: "Improves the BLAST radius of weapons".
