As mentioned in the forum post, the plane does not pars correct data, in particular the Alternates are not parsed correctly as to what Simbrief produces. Same goes with wind data which is now completely missing.
Up to 12.2.1 of X-Plane 12 this worked like a charm using the latest versions of Toliss. After I noticed some strange issues after initialization request (parsed data from Simbrief).
Is there any thing you can think of related to Simbreif?
Toliss is probably incompatible with planning more than 1 alternate in SimBrief. You will need to select only 1 alternate when planning your Toliss flights.
This is not a recent change on SimBrief’s end. Nothing has changed in SimBrief’s API output in quite some time.
