Error appears every time on carver table :)

I think i found some bugs:
- peons jump of the edge - i dont know why
- training center is training only to level 2
- industry can be upgrade only to level 4 even its showing option to upgrade to level 5
- peons running without any sense - why they dont not collect closest garbage?
- buldoger is falling from the map at the beginning
Good game with potential. I suggest that the description of books include a description with the required amount of mana, not just the level. Currently, the amount of required mana can only be checked after equipping the book and checking your statistics. The generated maps should be a bit smaller because walking takes much more time than fighting. In your own inventory, it would be nice if you could sort items by type, just like in a supermarket.
