One grid, but really two grids

I started a new grid with the J key on an asteroid. I placed on light armor cube to start, created a row of large batteries and then added solar panels. All was good. I then added conveyors and cargo containers. It turned out even though I had been using symmetry to create the base, one cargo container and half of the conveyors were out of alignment by 5mm. I could only tell where two conveyors connected, everything else looked aligned correctly. I had to grind up the left half of the new addition and rebuild it.

I thought I had fixed everything. I can add blocks everywhere and they are aligned pefectly... or so I thought. The batteries and solar panels are on one grid and everything else is on another grid. Hours of lost work. I decided to add new solar panels and remove the old panels and then would re-create the batteries on the main grid (that I never hit J for, only on the original block placed). This is all on an asteroid. I added new light armor cubes all around the base trying to connect the line of batteries to the what is now the main grid (full production line and cargo containers). However, the two grid remain individual grids. I even named one grid to tell them apart. It turns out the many hours spent re-creating the new solar panel array was wasted because they are on the grid with the batteries and not the main grid.

This is extremely frustrating because the two grids appear aligned perfectly and there's no issues placing blocks all around the grids trying to connect them together.

*When I take a blueprint, it highlights only one grid, not both. I will now completely destroy the battery grid every block that is not named the same as the production grid. I will then redo all of the work.

LOL - venting, but this is a serious bug that will deter people from playing when they run into issues with no way to solve except to destroy and then re-create. Also note, when I connected conveyors and cargo the many times, I tried to get them to share the same grid I made sure they were aligned perfectly, had the 4 green connector/surface lines which were aligned perfectly.
