Too bad alt, control, and shift click do not function properly on a consistent basis.
Too bad the game acts as if you are pressing alt sometimes when you are not pressing alt.
Too bad these things have been reproduced on multiple machines
Too bad they were never, ever touched across all patches.
It's always fun times to alt-click a group then attempt to use shift-click to remove them. Nope...just keeps re-selecting the whole group against your will.
Sometimes shift-click does this with smaller groups also, instead of selecting individual units, it just keeps selecting/unselecting the same group w/o splitting it. Of course others you can just select individual units this way...
If you have previously selected the naval units in a transport stack, control clicking a land or air unit will...KEEP SELECTING THE NAVAL UNIT. Merely left clicking at all will also continuously select the naval stack. You have to actually unselect the naval stack or you are stuck.
Sometimes one can whip every damn city, by simply left clicking on one city and pressing whip. Left clicking on one city occasionally means selecting all of them, even if you are soundly picking your nose with your other hand and it is nowhere near the keyboard.
Sometimes you also declare on your trade partner and friend who borders you and whom you are not defended against. When the game feels like it saying "you were pressing alt whether that's true or not".
In multiplayer and ONLY IN MULTIPLAYER (anyone know why this is?), you can not control-click to select all units in the same tile if some have used up their movement and not others. Seriously, it only selects the ones with full movement even if you do it multiple times. In single player it will not do this.
The game forces waypointed and automated units to move into danger that is readily visible, because THAT's fun.
Anyway, if you want something other than griping (which is hopefully likely), I still have my guide to speed civving in my signature
