at first I thought it was my newly finished add on that was causing the crashes, but then I suspected it to be slayer and looked on forums to see if there was anything in Help yet. turns out there was one topic with no replies, so I posted that it was slayer causing the crashes, assuming it to be a small bug.
it was a relief to know that the issue wasn't my add on, until a few hours later when I realized all my screenshots were missing lol
