Scorching Ray Graphic/Sound Error Crash to Desktop

It specifically happens when scorching ray hits a wall, which normally results in a flash of light at the point of ray/wall intersection.

Occasionally the flash is 100x brighter than it is supposed to be, sounds like it plays the sound file on top of itself 100 times, and crashes me to desktop.

I haven't identified the specific cause, but it has happened 4 times. 3 of them were in the chaos map from the device in act 7 for Silk, 1 of them in Haunted Mansion.

Let me know if any more of my info would be helpful.

(Thanks for the new portal saving technology)

5th Crash: Estuary(During Nightmare). The beam collision wasnt on my screen. No MTX used. Will start using Shaper beam

6th Crash: Dungeon(During Nightmare) Was using Shaper MTX this time
