Cannons Ready! and Nova Projectiles support gem BUG

When I have Nova Projectiles support gem socketed into a bolt skill (specifically armour piercing rounds), it does not register the projectile as valid for the totems to fire.

The support gem itself says that it does not support skills that rain down from above, but the support gem isnt in the totem skill, so it should work with cannons ready..

Can confirm, discovered this for explosive shot

Seems to be Nova projectiles' problem, not the skill it supports

Still bugged in 0.3c

+1 can confirm
