Unit counter does not update when units are garrisoned

[frapell]

When you select a bunch of units, in the middle section of the bottom panel, you get the portrait of the unit with the number of units of that type. Let's call this "Unit count"

when you select a bunch of units, say 10, the "Unit count" correctly displays the number "10". If you now send those 10 units to gather in some tower (or anywhere else), 5 will enter the structure, but the "Unit count" still displays a 10, when, in fact you only have 5.

The only moment when the "Unit count" gets updated, is when you have only 1 unit left without gathering.

I'm pretty sure you mean garrison when you say gather?

Either way I can confirm that the unit count on the portraits doesn't update, while the one on the shield does, so they must do something different in this case.
