OSX version 2.2.1
I only get that problem if I transfer scientists from one base to another. Upon transferring, it appears those scientists arent removed from the original base.
Work around, hire the scientists at the specific base they will be working at.
edit: for example, base 1 has 2 labs, I hire 20 scientists, base 2 has 2 labs, I select base 2, then hire 20 scientists. I never transfer personnel... only items. Personnel transfers appear to be a bit buggy still.
