Realized the same here. Lonely HE after update on defence. Set the defence back. Checked the issue you mentioned and restarted the game and lonely HE was set again. Hey NF, fix this!!! Really updates are getting worse and worse each time!
Edit: restarted the game after reset and again a lonely HE on PvP defence! WTF!!! Surely I’m not the only one, so devs would you please be so kind and give us an answer to this!?!
