The following rotation, for a survival talent build, results in a Runtime Error 13, type mismatch
Kill Shot 1 9.00 269 #DIV/0! 1.65 0.00% 51.53 #DIV/0! 5.22
Explosive Shot 2 6.00 269 #DIV/0! 1.65 26.53% 6.22 #DIV/0! 43.28
Black Arrow 3 24.00 121 #DIV/0! 1.65 6.40% 25.76 #DIV/0! 4.70
Aimed Shot 4 10.00 308 #DIV/0! 1.65 15.55% 10.61 #DIV/0! 29.00
Serpent Sting 5 21.00 454 5897 1.65 0.00% 0.00 0.00 0.00
Taking out the serpent sting "fixes" the error. Using the SS order for surv rotation ES/BA/Sp/KS/AiS/SS does not show this error. This occurs in SS 89f.
I take that back; sometimes the SS order shows the error and sometimes it does not. There are apparently two separate computation paths going on: one that updates the dps (somewhat inaccurately) when you change/update shots, and the correct one that occurs when you press "Test Rotation."
