What can be the reason for not being able to build a depot despite having the following in the region e.g. Oderzo (Italy) clear, mud, no structures:
- 2 active units of supply
- even an active general
- having the units there for a couple of turns
- 100% Entente alignment, 100% military control (Italy)
- not even adjacent to any enemy region
This is an example, at times it doesn't seem clear to me why it's not possible to build a depot?
