Yes 2.5. If loading employees is time consuming, can the Scientists and workers just be numbers rather than individual objects? Like a number of scientists, a number of workers.
Also i notice the save games include every single message (like aircraft returned to base, aircraft refueled, production finished etc) since the start of the campaign. Can it just be pruned to the last 10 messages? There is no need to store every single message.
I cannot delete excess pilots etc, right-clicking them has no effect.
