RB is not blocking World First Contracts
Need to see if it can be blocked. But I'm guessing will need similar treatment to how I resolved this for TST mod.
Example contract:
CONTRACT
{
guid = 509a08d4-967e-4b12-aac5-93935305862d
type = WorldFirstContract
prestige = 1
seed = 963019758
state = Offered
agent = Kerbin World-Firsts Record-Keeping Society
deadlineType = None
expiryType = Floating
ignoresWeight = True
values = 43200,0,118644.062280655,220338.972806931,140000,8,18.88,0,777969.024184557,0,0,0
targetBody = 6
targetType = FLYBY
PARAM
{
name = ProgressTrackingParameter
state = Incomplete
values = 0,0,0,0,0
targetBody = 6
targetType = FLYBY
}
