My guess is the coding of the random death that happens with the telescopes. It must need clear area to send the meteorite to kill the sim instantly. Having it on a covered balcony or the telescope inside just looking out the windows doesn't allow for the death.
An interesting point it might be for the meteorite! Well, I guess the code could instead allow telescopes inside but prohibit the meteorite from happening when they're inside?
The whole point for the new smaller telescopes was the new death type it introduced. The only way to prevent that death is to heed the warning and make the sim run inside.
