Every single thrall losses almost all his HP while im offline. So when I log in after work all my thralls are holding to their stomach and is at 5%-ish HP. Then slowly regens during my online time. Its like I have to “start them up” after every login. Please fix as my base now is comprimised

Steps on how to reproduce issue:

  1. Get a thrall. Place it in base
  2. Log out for say 8-16 hours
  3. Log back inn. Find every thrall you placed on defence at VERY LOW HP.
  4. Rinse and repeat (Not anyone can break into my castle and kill my well equipeed thralls with 1 hit)
