Recently (since the update?) i've had the following behaviour:
On arrival I can select a gate, and gate arrival/ guidance works fine. But after enginges off the GSX menu is stuck in LOADING and there is a oncommanded DEBOARDING REQUESTED call and deboarding satarts by itself (no jetbridge yet, doors closed). The deboarding 'does its thing, but no status updates and the menu remains stuck in LOADING throughout, until manually restarting Couatl from outside the sim.
Observed with both PMDG 737-800 and FENIX A320.
ps the forum doesn't accept .log files apparently, bit inconvenient :-P
