Looks like there's no more regular support from FSDT? And in any case, priority is clearly given to MSFS vs. P3D...
Well, of course priority is given to the sim where most of users are.
Not only that, you aren't even using a current version of P3D, and this issue is something specific to P3D V4, doesn't happen with V5 or V6 and doesn't happen with FSX or P3D1, 2 or 3 so, again, we'll check it when we can.
