If I use Adv. Storage, I get 20 Facilities with space for 24. If I switch off Adv. Storage, I get 24 Facilities with space for 20 (overload) ?
EDIT: If I quit SE and restart, this bug is gone; 24 Facilities in 24 slots. So I guess it happens if I restart games with/without Adv. Storage within the same SE-session only.
