Hi @SNBPilot,
w.r.t your “custom AI traffic compiled in bgl files by AIFP”, is this related to the Dynamic Flight Plan product from the Alpha India Group, or other product from that company? - Please correct me if I’m wrong.
Without knowing the composition of the blg & related files, this issue is going to be hard to reproduce. It may be that some change made to the Navigation/Traffic functionality in SU15 (see the release notes) has caused what you are seeing but knowing the composition of the blg & related files would be really helpful in order to attempt to figure out what is going wrong.
