Regular enemies health numbers not showing, and also non %/trap defenses not properly showing health numbers. For example; skyguards, blockades, flamethrower, sand viper, volcano, etc. Both are kind of minor, but I would rather see the numbers instead of just a bar that changes color depending on their health condition. These both have been issues since the Molten Citadel update I believe.
I found this happens on and off. I was testing how automation worked and at first I could see the health values of my spiked blockades but at some point they vanished. I'm not sure what it was that made them disappear.
