I've tried reporting this to the developers but the support form always leads to an error message.
I've had no reply to Facebook posts or messages nor to an email to bigben support.
The issue is on pc in the career mode.
I've had engineers and meteorologists disappear from the reserve.
I think this happens when you reload. Suddenly they are all gone except the ones that are active.
It doesn't seem to affect the other specialities.
There is no warning, no morale issue, some team members had only just been added and there is still room in the reserve.
I'm looking at running without both specialties at my next rally as there are none available to recruit.
Has anyone else run into this bug or have any suggestions on how to fix it?
Any help is greatly appreciated. Cheers
