This is probably a stupid question but do conditions disappear or carry over between missions in a campaign? Thing is, the rules specifically state the following on page 9:
Each Condition card lists when it is discarded. When this situation occurs, discard the card or token; the figure no longer follows the rules listed on the Condition card.
None of which say anything about post-mission clean up. And the post-mission cleanup says nothing about removing such cards either. Now I know that likely they are supposed to be removed, but with everything else being spelled out about what happens and when, its a bit odd that no where does it mention conditions being removed in any way other than doing the listed action to get rid of them.
