Do you think it would be a good idea to have intel on buildings never change when they are stealthed or outside of sensor range ? Meaning a building that you scouted will remain on intel screen and targetable even once it's gone, and building that gets constructed won't appear until you get a sensor fix (that is already the case), and buildings should not disappear from intel once a stealth field comes online (I remember reading here that they did disappear in that case).
Also second question, can it be made that way ?
