So, not sure if this is another instance of this bug or not, but it looks similar so I thought I’d add it here. When building a particular house, I had the familiar issue of windows not being placed. Then, one of them was placed. And after that, I saw all the other windows suddenly shown weirdly/brightly. See the screenshot.
Now, I’m actually not too sure if this is an instance of multiple windows placed in the same place, if only because I don’t think I had crafted that many windows. Perhaps it’s something like the windows being shown in build preview mode or something (or that whole house, with only the windows not being done yet)? However, you can see the house being built in the background isn’t shown that way.
