The team is aware of it. It's just that the screenshots show that there are buttons for quick army transfer, which is for people like Navukh, so they don't shout: "It's all your buggy TE!" :D
Why are you describing this here, smart guy? Did you just find out, and you can't wait to share it with the whole world?
There are dozens of such bugs in Heroes, and many people know about them, but teaching people about them publicly, in my opinion, is stupid.
This bug can still be caught by analyzing the save, but there are bugs that are almost impossible to catch.
That's why the portal doesn't publish a list of all the bugs in the rules!
And they ban people for discussing them.
