Just started having every wolf whose energy hits 0 (so any used in Hunts, for Explore, etc.) suddenly giving negative numbers for their energy. It is also consuming food points for said negative - ie. wolf is reading -25, give 1 Lettuce, energy is at -15. Tried refreshing, used a wolf for a hunt to see if it was just the two I was using for Explore, seems to be a widespread issue as any wolf hitting 0 is going negative. It may even be that any wolf going below 100 is showing an extra loss, as my mining wolf is having the energy bar jump lower when I reload the page (it doesn't normally do that).
I'm on Opera, Win10. Everything is up to date, and this issue just started in the last 20 or so minutes from this post.
**Just fed my mining wolf to 87 energy, went back to the smelter, and it took 50 energy instead of 25. :/
