Towers not captured, nor City (protecting Sandworm vanished)

[Maze]

Game-id: 21161
Player: white (Maze)
Attacked neutral city with hero + 2 units, neutral city defended by Sandworm. Attacking the city, the battle screen shows an empty city and when closing the Sandworm is happily present in the city, as well as my stack. Two seconds later, on the screen, the Sandworm vanishes LIVE (= did not press anything, no other screen etc.).

Before, maybe this is related to this bug, I attacked two towers (if you have a look, you will see which ones) on my way to the city, which weren't captured. On the first tower, the battle/info screen opened but didn't show anything, while the second tower was just there as a graphic but the battle/info screen wasn't even opened. On both towers, my hero didn't get xp (I think).

I will wait for your feedback before proceeding.

EDIT: re-opening the game shows me the Victory screen, allowing me to occupy/plunder/raze the game. I just closed the screen again as I don't know if this would complicate your investigation as I am not sure everything is solved with this "refresh":
- Are the towers also captured?
- If so, did the hero get xp for this towers?
- What happened to the Sandworm? The battle screen showed empty screen and 100% odds, so was there or was there not a Sandworm? I guess the graphic showing the Sandworm in the city was not wrong. Was the battle screen wrong and the battle itself processed correctly? Or was the battle itself wrong too?
Etc.
