a few game breaking bug fixes

CHANGELOG:

today 13.08.18 I released a new version of the game. I did not add any content/features! I only fixed some gamebreaking 
bugs:
- when expanding the warehouse tiles were not updated correctly so the ai did crash or behave weird
- made changes to the ai so it won't get stuck in certain tasks and stop working
- removed a debugging command that gave unlimited money in the shop
