The rule says the game must be on the current version, but in parenthesis it says 1.6. Does that mean it has to be 1.8.2 or can it still be 1.6? I don't want to upgrade and lose BLSS.

We are currently making revisions to the boards. Everything should be up to date by the end of the week this week. If you want to see how the board will look along with the new rulesets, check out the Base Game boards.
