Another annoying interface bug...
The mouse pointer is not visible, but it's hovering over the selected meatman's monster tab. Predictor shows health increase.
This is not actually a predictor bug: I noticed that there is an issue when I clicked the monster portrait, wanting to switch back to the on-selection UI, and instead of switching tabs, it drank a health potion. I'm not even having my inventory tab open. EDIT: not sure if it matters, my health potions are sitting in the 1st small item slot of my 5th inventory slot.
I'm playing the web-based version.
"Thinker", just without the "ache".
