BUG: Click adds troops per slider, not per quantity.
This matters when scouting tiles ...
Pick a tile, then espionage:

Click in quantity box:

Click send (as 1 troop is showing to be sent - by slider, at least).

Result:

Bug.
Either ... don't move the slider to show 1 troop (having clicking in quantity, obviously at least 1 troop is intended to be sent, so moving the slider makes sense), OR, also update the quantity to '1'. (Rather than 'merely' indicating with '|' the preparedness to accept a number.)
This would let tile espionage be much faster:
(Since tile scouts always succeed for lack of on-site scouts to oppose them.)
- click tile
- click espionage
- click informer quantity
- click send
