Hey, I might have actually solved this. I was having the exact same problem as you, as I stated in my initial addition. You'll have to check on your stuff, but for my issue it actually ended up being a problem in the ELS file. I had tried to set the extras in the "extras active on cruise mode" section to 1, 2, 7, and 8, instead of the traditional 1 - 4 they all seem to come with.... seems like theres a reason I never see any ELS files that have cruise extra options anything other than 1 - 4. I switched the 7 and 8 back to 3 and 4, and my pack works again, no crashes. If you have that packs ELS file installed, maybe try installing it again cleanly and see if your issue mirrors mine. I hope this helps!
