I keep mining regolith along my upper transit tube, well i used to, and it keeps falling in. despite 2 floors between space and the tube.
I did some testing and learned that the tube doesn't get blocked (and obv not melted in this instance) by the falling regolith so i'm going to switch to ignore it
but it is enough of a bug to report since it is very illogical and could potentially cause heat and other problems,.
edit: I do not use fast forward of any kind normal time flow only.
build as shown (upper layer of bunker, two lower spaced-out layers of a normal floor and come back after awhile. find more regolith
