[[V1.63 (GOG3) - Linux - Geoscape] Unable to assign soldier to dropship]

With my current save game I am not able to assign an unassigned soldiers to my dropship (although there is enough space). Second, I am not able to rearrange the soldiers in the dropship before going on a mission. I saw some older threads about this issue but they seems to be caused by a version mismatch of Xenonauts. I started with V1.63 and I am still using it.

Is there any solution/ workaround?

The same behavior is found within the Xenonauts launcher if you specify an alternate save game path. The value does not get stored and you have to reenter it every time. I am using the same version as the TS.

I am using GOG version 1.63 on linux (downloaded and installed last week) and have the same error. Are there any news on this?
