Okay, let's say all is well.
Cash available 4M after gate leasing
You mention you sold your Beech then ordered an a318 , correct?
So you went to the airbus purchase page with (well let's say you got 14M for your Beech, not possible but let's pretend it's a nice round number) 4M + 14 M is 18M , let's say for arguments sake you did not get your gates yet so you have 5M in cash.
That is still not enough to order an a318 , so how did you order it? If it's a bug then report it?
Now step 2
You now have 0 cash and 1 Beech left , (well let's say you got 14M for your second Beech, not possible but let's pretend it's a nice round number)
You now go to the Bombardier order page and or 2 q400's for 19M ?
How did you order them?
If it's a bug report it and add the steps you used!
Well looks like the bug has already been reported doesn't? Furthermore, I don't have a damn clue as to what steps were exactly taken. I did not knowingly take advantage of a bug. The issue didn't occur to me until I was called out as a cheat on these forms.
