Soulash v0.2.6 Version check

It's been a month now since Soulash release, and my focus will be shifting more and more toward working on the major v0.3 update. In this patch, we'll have a notification on the main menu screen inside the game if a new version of Soulash is available for download. There have been some updates to the world map, most notable being performance improvements after uncovering more terrain. And as always, we finish the list with a list of bugs and crash fixes. A standard reminder that most of these changes will be applied to new games to avoid breaking saves accidentally.

Oh, and one more thing. There is now a Discord channel available for Soulash if you would like to ask for help or chat about the game: https://discord.gg/Y2dwG4c
