Small Grid LARGE battery not airtight (Aug 7, 2020)
I went to work on a small block build that I had previously used shutters on for doors. I wanted to try the new small grids doors. They worked fine.
Aspart of my testing I checked airtightness. I no longer had it. I verified it was lost with the orig build and shutters enabled. It was no longer airtight. It was fine a number of months ago when I last played.
I removed the doors and filled in with blocks. Still no pressurization. I have a sidewalls that were exposed battery instead of armor just for economy of build. I removed the battery and filled it in to test and all was airtight.
Small Grid LARGE Battery was the cause of the loss of airtightness.
