Noticed when checking a bug report by tiber.

If the shield on an auton is recharging when it is in the auton bay (charged state increasing in the screen desc) the mouse rarely operates the actions for that auton without, at minimum, several seconds of delay. Often it won't operate the action at all.
Strangely, selecting the action by pressing the relevant key on the keyboard nearly always instantly operates the action.

Also noticed the same lag behavior if the armor is self-repairing itself.

Both the mouse and keyboard actions operate instantly once the recharge/repairs finish.

For other autons in the same bay which aren't repairing/recharging the actions operate instantly with either mouse or keyboard.
