This is turn 13. Zombie Spy is face up in the trash, but there is no highlighting around it and I can't click it when I play Necromancer. Weirdly, when I choose the Necromancer in the trash with Necromancer, a highlighting appears around Zombie Spy and I can click it. (you can't see the problem from the log, it just looks like I'm a weirdo, but it's this game:

Thanks for the report.
I'm betting you a handful of Ducats that you used the right-click feature to look at the cards in the trash, inlcuding one Zombie, and then, maybe by accident, clicked on the Necromancer card that also shows up then. This has currently an unintended side effect of 'deactivating' some cards, which you witnessed. Once you play the other Necromancer, this is a new selection, so everything works out again.
