[Structural Integrity Issue]

OK so it seems this bug is already known about. Skippy's Youtube channel explains it. But essentially as I went around the foundation removing sand and replacing it with concrete the structural integrity would update when the sand was removed but not repair itself after the concrete is added. So once I removed the last sand block in the corner that was essentially holding up the base, the base collapsed. I was unable to reproduce it above because when I rebuilt in GOD mode I didn't repeat the removal and replacement from the beginning. I only repeated it for the last 3 blocks.  Why did the base collapse even above solid concrete? Because the replacement concrete was not recognized. This is game breaking for sure. Once any block is broken out in your base and you have replaced it, you must go into dm and update the structural integrity.  Otherwise these structural weaknesses will build up over time and your base will collapse as if you never fixed it in the first place.

[Structural Integrity Issue]

OK, I rebuilt in God mode. After rebuilding I had no structural integrity issue at all. I removed the sand a second time to cause the collapse and nothing happened. Sorry. I could  not reproduce. A strange side effect was when I replaced  the generator and traps and  switch, the electrical wires spawned in on their own. A couple were missing and I could not reconnect the wires. But it all worked. Electricity was flowing but I couldn't changed the wiring. During collapse the wiring info remained as a ghost  and glitched back  in after reconstruction. Anyway, not sure what to do here with this bug, I guess it can  be filed  in the X-files.  Note: I still think  the chain reaction collapse should  be removed. Only  collapse the blocks that  fail integrity. Don't let it spread to blocks that are on solid foundation.
