Hello respected community!

Map Editor is out for few days already and I've spent most of the time fixing bugs that has been reported by you.
Thanks all of you who helped me finding these bugs and by sending also save files, you made it easier for me to fix it quickly.

Wow, you have reached the end! Thanks a lot for your time.
Finishing editor after so many weeks was like releasing some stone I was rolling in front of me for a long time. I know it was even more difficult for you, since having so minimum insight into the development from outside is not fair for all of you who already bought the game and I will do my best to keep you involved next time, because only together we can make the best tycoon game ever ;)
Have a nice day!
