Glitching parts upon testing/playing game?

While developing an upcoming game, I am experiencing a glitch that occurs when I test/play the game in studio. Below are a few photos of a glitch that I am experiencing. Does anyone know why this would happen and a fix to it?

Another glitch from what I assume is the same cause

What it should look like

Are you sure these parts are anchored?

Just noticed, the parts in the first images were not for some reason. The road lines, however, are.

Perhaps try unanchoring and reanchoring the parts.

Nope, no luck. I did notice that when I duplicate them in place, then test, one stays put and the other glitches out. But when I move one below or something just to cover it up to see if that fixes it, it goes back to glitching. It’s confusing.

The parts don’t seem to be anchored.


They’re anchored.

Are the yellow parts too deep into the ground?

No, they’re above ground. Either way that shouldn’t cause it if you have it anchored and collisions off.

Have you tried restarting studio or your computer?

Hi there,
Could you show me the Properties of the Parts?

I don’t think that would do anything.

This is weird. Add me on Roblox, and Invite me to a team create I’ll see if I can help fix the issue. It’d help seeing this in person.

I found a makeshift fix for it for now. It kept occurring, but if you duplicate it then one stays put and the other glitches out, no matter whether you delete the glitching one. I basically just figured out the glitching one of the duplicates, and made it invisible and cancollide off. It’s quite confusing, and it’s happened before with roadwork.
