Exclamation

[HOTEC]

My unit's 120 (3 HQ + 5 Large + 1 Small) strength matches the port supply level (6+2+2)x20.
Why do I still get the exclamation mark?

[generalfdog]

it means the port is maxed out and can't effectively supply the units that are drawing off of it

[AlvaroSousa]

That is a port 2 supplying 50 strength points of units

10 for each HQ and 30 for the corp. It can't support that many strength points of units with supply.

[HOTEC]

Let's say from the top.
The top one is Port 2x20. It should support 10 for 1 HQ and 30 for 1 Large Corps.
The middle one from the left is Port 2x20. It should support 10 for 1 HQ and 30 for 1 Large Corps.
The bottom one is Port 6x20. It should support 10 for 1 HQ; 90 for 3 Large Corps and 20 for 1 Small Corps.

Still, I don't get it.

[AlvaroSousa]

This looks like you conquered Finland and Sweden. If so then yes you have to draw port supply from everywhere.

[HOTEC]

Yes. It does not work.
Still, get the exclamation mark.
Why?

[AlvaroSousa]

You exceeded the port supply with the units there.

Also there is no rail connection from Sweden to Finland. So their supply doesn't reach those units.

[HOTEC]

Should the units close to the port be supplied first?

[AlvaroSousa]

It gets divided equally if I remember.
