The completely unreliable unit selection interface causes a massive unit loss.

I just send all my champion units alone to attack a emporium.  I started by selecting 16,000 Agemas and 20,000 Promachos but the ever present interface bug un-selected the bulk of my attack units and sent the champions alone to attack the emporium without the regular warning that champions should always be sent as support to regular units.

This is totally unacceptable!  This problem needs to be fixed and Plarium owes me a refund for all the lost units.

The same type of issue affects all emporia attacks even small ones where the selection process "forgets" some of the units selected. It usually results in an innocuous message saying you need to select both offensive and defensive units to capture an emporium.
