Hello, during my testing I build around the advanced status effect Overload (fill the burn bar to full, hit with lightning for big boom). I sometimes felt like I took a lot of damage, at first I thought I got hit by enemies but today it happened again against the casting prisoner enemy and I was sure I did not get hit. I tried to recreate it a lot and was not able to until this. The clip shows clearly that I got hit by my own overload.
My best guess, maybe the code for friendly fire, does sometimes not see me as the source of the overload
Edit: Another proof
