MTA fixes:

- It is now possible to talk to the telekinetic guardian through the maze wall.
- Asking for the price of an MTA reward no longer attempts to purchase said reward.
- Graveyard bones now give the correct amount of bananas/peaches.
- Number of telekinetic mazes solved now persist when exiting.
