On long flights (eg EHAM-KSFO) the time display on the FMC flighplan page is corrupted in the latter part of the flight (both 2020 and 2024). I have not determined precisely when this happens.
I have installed V1.1.3 of the A300-600 in both MSFS2020 and MSFS2024 using iniManager 2.4.1. No problems in 2020, but the plane is not visible to select in 2024, despite being installed to my custom Community folder.
