Small bug: there's an inconsistency with whether or not a player retains control of a town when it loses all of its civilian population. In the screenshot below:
- Emptied by training the last 50 Orcish Swords.
- Lost its player banner and control as a result.
- Emptied by placing a unit of Wolf Riders on it.
- Still has player banner and control (I have the option to donate it; persistent through refreshes).
I'm not sure which one happens if a town gives up the last of its population to a remote deployment (at a Banner).
As a side note: if a town loses all its population (and thus, maybe, its player control), but later regains some population, does someone have to go claim it again?
Edit: turns out that I can, in fact, donate an empty town, as long as I emptied it by dropping a hero on it:
