If anyone sees a building disapear check the registration hex ( typically the upper left hex of the series it had been in ) BEFORE it is saved and let me know if hovering the cursor over that hex shows it to be rough and after you save and restart does it show "paved"

The theory I am exploring now is if the registration hex is turned to rough that is when the building disappears.

After saving and restarting the building will be restored but report the hex under the registration hex is Paved

IF you build a map and place a multi over a rough hex the registration hex ( and some others usually ) will report "paved" and I think that change to rough during as bombardment might be the key to why they disappear

SO FAR I have not found a multi that shows rough under the registration hex
