Asobo, please get in touch with AIG (Alpha India Group, freeware AI traffic), AIFP (freeware AI traffic creator tool) and FSLTL (freeware model matching for live traffic in msfs) and ask them what they need.
I also found out if you generate a flightplan using AIFP with two liveries on the same model it will randomly pick one livery and apply them to all models. (the issue is not on AIFP’s side) This should also be fixed.
