yep, I have this problem also.

For some time whenever doing a capture on an emporia, their is a bug.

It is getting more prevalent.

You select Off and Def troops.

Firstly they are often not recognised (see screen capture).

Selecting/deselecting a Guardian will affect this behaviour.

Even more frustratingly, other action reports happening will affect troop selections, so (1) You find yourself chasing your tail trying to select the troops you want, (2) You can find yourself sending only a portion of the troops you had originally selected.

Please fix

Thanks for bringing this to our attention, agesofman Red Warrior. I've already reported this issue to our developers. I hope they'll manage to reproduce and fix it.
