Sandbox glitches

Hey, sorry if this was already sent or anything, i just got the game yesterday and i am new here

Anyway, i've been playing on all modes, and it seems that sandbox has two problems that happen often, at least with me. They always occur after loading a save from the menu, and the only way to fix them is reloading the save over and over until they disappear. It only happens if i have sandbox on the save. Also, if any of these is somehow a feature, please tell me, and i am really sorry if they are

Shining metal tile

Sometimes a few metal tiles have some kind of bloom on them (they shine) and them, including all other nearby metal tiles will be ignored as if they weren't there in the first place. Buildings will have that warning sign that they are in mid-air, and duplicants won't be able to go there. It doesn't happen with any other tile in the game.

Missing pipes and wires

I noticed that pipes and wires that are near objects' "outlets" sometimes just disappear and you gotta rebuild them. It's kinda of annoying.
