Patch Notes v0.5.1

This patch brings fixes for some of the bigger bugs left behind in the wake of the Apocalypse, as well as some quality-of-life changes for combat. [list] [*] Added a single-card discard for 1 pip of action time. Click a card in your hand twice to discard it. You can also now deselect the active card by right clicking. [*] Fixed a bug where cards in the crafting screen would show the wrong descriptions. [*] Fixed a bug where the world map could be clicked through the craft screen. [*] Reduced the density of rifts in the late game to congest those battles slightly less. [*] Re-added a grid to the battle map, with slight visual tweaks. [/list]
