Grid Deleted or Removed

I've been playing the Welcome to Verdure campaign for somewhere around 14hrs give or take. I've been doing contracts and after finishing the Construction Site contract where you fully build 2 grids for building A and Building B, something like 118 and 87 blocks each, I've been coming back to that location to use the smelter and assembler. The location is almost exactly 45km from the Space Station over Verdure, in case that helps identify where I'm talking about.

I just scavenged enough lead and magnesium to finish the contract for the Weapons Delivery, and came back to said construction site to use the gearforge there, and when I arrived all of the blocks on both grids were completely gone, however the mining ship and welding ship were still there. I have no idea how or why they were deleted but I assume it is a bug or a memory glitch / issue. I remember in SE1, unpowered grids would be deleted by the garbage removal backend code, but I don't think the grid I'm talking about now was unpowered.

During the time I was scavenging, I also noticed that I would frequently lose the ability to open doors, access storage blocks, access production blocks, or really interact with anything. The only way to fix it that I found was to save my game and reload the save. This happened more and more frequently before I discovered the deleted grid(s). I don't know if it's a related issue, but still a bug nonetheless.
