No towers dropping

On my current run, I've just passed round 400 but have realised that although the text says tower cards are dropping they're not in my inventory. Annoying as I want to transmute them!


Same here, just noticed this today as well. Was using only metro towers. Wave 60-80ish only purple towers went to inv and money bins

I think you probably double tapped them for auto-transmute. You can check by long pressing the towers icon in the stats screen of the game. There you can also undo auto-transmute. And when double tapping, you can choose how many of this card you want to keep on your hand.
