I approached some drivers yesterday (5 in total), but didn't sign them yet because I went offline.
Today I got the message:
"More than enough time has passed to sign a contract. I will review my options elsewhere."
When I try to offer a new contract (to some other driver), I get this message:
"You have made the maximum number of offers. You can make more offers at the next race."
Which basically means I can't attend in the next race because I have no drivers? (which is still 2days to go)
I know it's not really a bug, but I think something should be changed..
