First print from coldstart Z-Offset is bad... after that, all good

[indigo star]

So I recently re-did some of my print_start and mesh and QGL routine and all that, adding in the adaptive bed mesh system from KAMP.
Overall it works great except for one small issue. If I start the printer from cold (motors off), the first attempt at printing results in a bed mesh that is way too high.
After cancelling the print and starting it again, the Z-offset is good. Every subsequent print as well.
I feel like it's most likely just something about my print_start order or something missing or out of order, but not really sure to look.
Any ideas?

the print_start would be helpful
