Merchant of the Skies - 1.6.5 - memory leak

Hey Merchants!

Thanks to a random youtube comment, I think I figured out the source of crashes that troubled some of you. I'm pushing a patch that should prevent a big part of game crashes on some computers. Thanks to everyone who let me know and I hope you keep enjoying the game.

I'm back to my vacation, will answer all the inquiries after May 18.

Cheers,
Vladimir
