Crashing with Molten Strike

I've been running maps for the past few days since the latest Patch was released with no issues whatsoever. I am also running a
molton Strike Build. Tonight, however I have had 4 crashes Whenever running a map that contained an abyss or a breach. I have also noticed a significant lag between casting my molten strike and it hitting the mobs that were rare spawns Or had any modifiers. Thus resulting in numerous deaths, glitching, and resetting to a previous point. My gamertag is MasterPress.
