Getting Tasered Doesn't Let Me Heal to Full Health
If you're using a model with more than 100 HP and get tased (which happens quite often to ogres) you cannot heal back to full health above 100. Also, it seems like your health goes down to 100 maximum even if you're not stepped on / shot at.
Get tased with Shrek or any the GM Sniper model and then try to heal via a health station.
