Lease fees refunded (totalling to 2,000,000) and any remaining errant leases associated with 4416 have been disabled. Sorry again about that, we really do try to fix bugs as soon as possible.
clicking the view link works for me for anything with over 0 in either the debit or credit column, even in your account. It should show all transactions of that type in your history.
DOP, Daily Operating Profit. Slightly different from Total Profit, yes, maybe a little confusing. Sorry about that. it's now, however, a pretty commonly known term. You'll see it not only here but in several other airline simulations out there. I'll think about amortizing leases/gate fees and incorporating them into this number, but it might not happen for a few weeks.
24 hours = 1 game month, 1 hour = 1 game day, all game months have 24 "days" yes. a conceit made to keep it relatively simple and consistant.
With regards to proration: Gates, yeah, sorry it's never prorated, ever. Unlikely to change in the near future... so many things to do (unfortunately). Leases, unless returned early you actually gain a few days on the lease. Assuming it runs through to expiration, it will only process as "ended" on the 1st of each month, so if you rent it on the 17th for that month you only pay for the 17th-24th. however, the last month, you pay for 1st-17th (when it "should" be returned by the counter hitting 0 days/months/years left) and youu get the 18th-24th for free. if returned early it's not prorated. that's the closest thing in the game to an early cancellation penalty (and it's pretty mild compared to most all real penalties of the type).
Please don't take any of this as me shooting down ideas for my own "brilliance" or what-have-you, at the moment i'm working on a system to get multiple worlds going at once (to ease some overcrowding in the game) which requires around 225 files to be updated... little daunting, little time consuming.
