Maintenance costs for depots at sea

[Dancing Bear]

Hi all
I think there may be an error in how maintenance costs are being calculated for depots on ships providing invasion supply. A depot should cost $1 to maintain, no matter where it is, but when I look at the maintenance cost totals in the income summary, they don't add up and I suspect that we are paying $5 per depot at sea, which is incorrect. (i.e. if I have a depot at sea my maintenance totals appear to be $4 more than they should be). Can anyone else confirm this?

I ran a test game, and the maintenance of deopts at sea is working as it should ($1, not $5), so this is fine. There is no bug here.
