Ok guys, I can now confirm the following !
ortho scenery from 2 different drives crashes something in xplane but the error gets thrown from the tbm, so that is on laminars end for sure.
i removed my ortho links from the custom scenery folder and it all works fine !
Added them and boom crash, sometimes after 10 mins, sometimes after 8 hours.
So I can easily recreate this and fix it.
since I read a lot of logs where something with the custom scenery is strange, I suspect it has something to do with that and that is something that has to be forwarded to
Laminar, I guess ? cheers
