Weird bug ("double god mode")

[Egoyte]

Hello.

So I'm playing Tower Wars, like I do. Losing, like I do. Then when my castle crashes down, last of the health leaves it... the game doesn't end.

As confused as I was, my opponent dropped his maze to let my creeps through, to see if the same thing would happen to his castle. It did. My creeps destroy it, we see the animation of the castle falling... and the game doesn't end.

While I'm relatively new to the game, this was the first time I saw this. Was wondering if it's a known bug, or if I saw a unicorn?

It is a old thing.
As I know it is related to the process of reporting the end of the game to the steam servers. As I know the scores are recorded well and you can finish the game simply with surrendering.
