Recent BattleCON games had a couple ambiguities or errors, which are addressed entirely by this one-page reference sheet, which we encourage you to print and keep in your game box: 

For a limited time, replacement cards with these errata (excluding reference cards) are available for free via the Empyreal: Far Corners Pledge Manager. To receive them, you only need to pay the cost of shipping (and any local taxes due upon that shipping).

You can register to receive these cards via the Empyreal: Far Corners Pledge Manager here. Use the "Participate" Tier to join the project at no additional cost.

The errata will be available through this channel until the Empyreal Pledge Manager closes. That will probably be around August 2021.
