Not sure if this is related but it might be.
When I place a Viggen on Bodo airbase (9075) as Start from ramp, the FR22 base selector turn wheel will just scroll up until the end and stay there. It is then not possible to change it.
If I place the airplane on Jokkmokk (9067) instead, it works perfect.
Might be related to the to many airbases issue.
