Mage Knight - Intermittent Tactics Cards Problem

I have little hope this can/is gonna be fixed, but here goes:

during solitaire play the module occasionally fails to show the last 2 night tactics cards, which should show up after the last round change (after you click on “solo scenario round end”).
I don’t know what ‘triggers’ this problem/how to produce it.
