I always have more than enough points for at least ONE Arado, but it will say I don't. I could have 100 perk points, and the AR234 be 83 perk points. I click on it and it says I don't have enough perks for the plane. Sometimes it does, sometimes it doesn't. When it does for prolonged periods of time it gets a bit annoying. I open up the hangar to check and see if the cost has gone up but it hasn't. Does anyone else have this problem?
