Hero Splitting

I personally observed the duplication happening twice, in online games. Both times, there were 9 or 10 heroes, and the hero located in the castle was duplicated. The most unpleasant thing is that one weak hero disappeared from the hero list. Luckily, it wasn't a hero participating in the chain, but a scout.

Here's another interesting thing that happened for the first time (save file attached).
In the second game, Christian scouted a tier 3 resource, died there, but his spirit continued to guard that resource for a week. If you release Christian, the game crashes. I had to kill him.
