Flights and locations:
Back in the day, fighters has to book a flight to get to the fight location or else the fight would be a no-contest. This has been changed, but in a bit of a messy way. Because lots of NC were happening because of this, the owner of the game decided to add figher teleportation meaning that no matter where the fighter is, he will always be come fight time at the correct fight location. This means flying is useless!
There are howerver a couple of side-effects: If your fighter is not at at the fight location 2 or 3 days before the fight, you will get an message with a warning about this. Ignore this warning. On the next day, the game will automatically book him a 2nd class flight to the fight location. The cost of the flight will come from the fighters finances. You should always cancel this flight. You can do that on the Map page under schedule flights.
1 - Ignore the warning message you get if the fighter is not at the fight location.
2 - Make sure there are enough funds on your fighter to cover the auto-booking. (if not, he'll be kicked out of his gym)
3 - Immediately cancel the auto-flight on the map page. 80% of the cost of the flight is refunded to the fighter.
4 - Just wait until the fight. No need to do anything anymore.
