OK, I made the statement:
"Everyone should stop using GSX temporarily until further notice or until further updates come out for FSX/P3D. Please use FS2Crew's UGCX for Pushback and manage fuel & payload manually without using GSX when flying. Also use PMDG's Ground Services, (if possible, use PMDG's Pushback system or the Self-Drive Pushback truck or UGCX for Pushback) if flying PMDG Aircraft, instead of GSX. (NGXu, QOTSII & 777X only)"
We must wait until GSX for FSX/P3D is updated.
