v0_6_6_1 Patch Notes:

Some people were experiencing a bug on Linux where worlds would be completely covered by Tundra tiles upon generation. This caused the game to be virtually unplayable as Tundra isn't yet available.

This bug was occurring because of the way we load game data depending on the region you're in. Some regions use (,) commas instead of (.) decimals to represent floats in strings. i.e., 1500,24 instead of 1500.24. So, in those regions, they'd try to parse the values to their own float representation and this would cause a mess. Now, regardless of region, floats will all use the (.) decimal representation to fix this problem.

To those that experienced this frustrating issue, I apologize! Thanks for your patience while I tracked this down.
