You may be right.
As for me, I changed the whole package 9.6.13.267029 (exe, data, branding, ...) to 9.6.13.405, only kept sys.txt that I used since... I don't remember even the year.
The only build that crashes with that sys is 9.6.13.267029. Igo8, Primo 1.0, 1.1, 1.2, 2.0, 2.4 (except 267029) all perform well. Must be the combination with the device.
