Parts rotate from their original position once online

I had this issue years ago with rollercoasters. All parts are anchored and I believe it was a bigger issue with flat shaped parts. I’m bringing it up now because somebody on /r/roblox was having this issue just today. He provided this test place. Basically parts will shift in rotation, I don’t think they change position, and they only do this in online servers. The parts can be anchored, cloned to a new file, near to 0,0,0. Nothing “hacky” seems to fix this issue. Keep in mind they only shift once. They don’t continue to shift as you play the game.

For more information, you might need to check with the guy on reddit, I told him I’d post the issue here since I’ve had the problem many years ago and he’s not a part of the developer forums.

Thanks

Not the C-Frame glitch again. That was the worse glitch ever.

…But this seems different. With the old C-Frame glitch, the parts would rotate and one side of the brick would be move up and the other side moved down. With the place he provided, all the bricks seem like they were moved, not rotated. Like in this image

Both sides of the part I’m standing on seem to be lowered, which wouldn’t happen with the original C-Frame glitch.

EDIT: Nevermind. Was focusing on the small brick, not the larger ones

EDIT 2: Can confirm that the glitch is not limited to the place you linked. Found it in atleast one of my places, checking others.

EDIT 3: Ok. Have two repros.

CFrame1 doesn’t have the glitch, CFrame2 does, both are exactly the same as far as I can tell.
