Version 0.6.3.51 (EA Beta)

Hey everyone! Here is a small update but with important fixes of the game stability. Last month our team was working on important features such as a new flight generator, airline contracts UI, flight contracts UI, terminal constructing, new terrain, Chinese localization, airport decorations, and fixes for this small update.

Not all features are ready yet and we still working on them. Next week we plan an update with the Chinese localization, new flight generator and terminal decorations. Also, we plan to make a new beta branch to let players test terminal construction (without terminal services for now)

All these features we plan to finalize in Jule. Also, we will try to add a new era to make progress until 2000. But there is a chance that the new era will be available in August.
