I can't find a description in the rules and I assume there's a really obvious UI element that shows you're about to overheat but I can't seem to find it - can someone point me in the direction that signposts this key feature of gameplay?

Current version: 1.1 Important changes in 1.0.3: - Flux Defluxer was nerfed, and now costs more shield capacity to deal damage and the other option gives less shield capacity - The old Temple Ruins event is now back. It was previously removed because a new temple event was coming soon, but until then, the old one is back on the table. The new redesigned temple ruins event will probably only come in the 1.1 content patch - A new random event: A friendly Aylon ship is giving you free cards! - Other existin...

Using Nova Jet with an x cost, 1 cost and 0 cost card in my hand resulted in the enemy taking nan damage and their shields stating nan damage. Cards - Overheated shields, Energized Drone, Rocket Rain Energy was 4. I also have a screenshot.. enemy was 45 hp with 10 shields....
