Yes, I already noticed this. It seems that the remote control must be a virtual item if it is to be used in map mode. This means I'll have to remove the recipe, change item flags + effects of the unlock tech, and define shortcut + custom input to put the remote control into the player's cursor stack (already done). I'll also have to make some changes in the control stage, e.g. for activating the shortcut. Hope I'll be done with this soon. :-)
