Ultimate HD Fire Effects
Ultimate version still causes CTD.
I noticed some frame drops when using the starter flame spell at first.
Used the flame on a beehive hanging off a tree and got a CTD.
Flame atronach also cause a ctd on using their spells.
I disabled the following in MO2 and it no longing crashes.
I've tested this in my game and have not recieved with CTDs while spawning multiple Flame Atronachs. Nor did I get any CTDs when roasting bees, beehives on trees, beehives from Golden Glow Estate, bushes, skeevers, Lydia, etc.
Be sure you are only using the version I specify in the instructions. For now, I'm closing this bug unless more reports come in.
