Hi Ramza, so sorry to miss your message. Been kind of busy for the last month with my day job.
I found the error causing the crash and fixed that (I made an error in the formula for "additional parry chance". However, the parameters refuse to display...except then I realized that I was an idiot and forgot to add the ExParam Display Fix (DW edition) plugin. Once I added that, it fixed everything. So sorry to waste your time on this, and thank you for your patience with me on the issue I raised.
