Triggerbots Not Working Properly with Vortex of Projection

Hello, while leveling a spell slinger vortex of projection sab I noticed that not all of the frosts bolts were being consumed.

After some quick in game testing the trigger bots correctly cast both vortexes, so 2 frostbolts are consumed, however only one of the two vortexes continues exploded off of frostbolts, so out of 10 frostbolts only 6 get consumed. it does not appear that they are somehow exploding off of the same frostbolt from looking at the damage however I could not verify myself.

Hopefully this can fixed as soon as possible, thank you for your time!
