XHP flash with JB4 on (whoops)

Hey guys,

Yesterday I went and did a MHD BEF on my car and updated my stage 3 XHP transmission tune to the recent version. Like an idiot I did the backend flash first and it worked great, and I then put the JB4 on Map 2 after. Without thinking I went and updated the transmission tune to the latest firmware, and I left the jb4 on Map 2 while it was flashing.

The xhp update worked flawlessly too without problems, and when I turned the car on the car went from being on Map 2 before the xhp flash to being on Map 0. I've since turned it back to Map 2 and driven it for about 40 miles and everything seems fine, but wanted to know if I could've possibly screwed something up with leaving the car on Map 2
