As before, when making certain specific items, red errors occasionally occur. Once this error occurs, the AutoMachineTool making the specific item will stop working.
You can only continue to craft that specific item by removing the AutoMachineTool and rebuilding a new one.

Today, when I entered the game developer mode to check for errors, I found that there is a kind of white errors that constantly jump out. The content is similar, but it does not affect the game.
Here are two of those white errors.

first：

I just found that the white errors did not reappear,
but the previous red errors still appeared.
