I was having crashing issues last weekend when I started running juiced delirium maps. I too am using tempest shield, but I found that the problem was the MTX "Ring of the Demon Slayer" that was causing me to crash. I turned off that MTX and I have not crashed from delirium or anything else since and its been almost a week. So my suggestion to yall is to check your MTXs.
ahh, i did have that equipped, gonna remove and try again. thanks for the info
