Meshpart with bones ALWAYS appears in wrong place on mobile, and appears COMPLETELY distorted/stretched!

I have a trampoline that I’m using 2 bones within to animate bouncing up/down as you jump on it - On PC, it looks like this.

My mobile phone users reported the trampoline to be missing, though, and EVERY single mobile player including myself who has tested this reveals the same thing - The “Middle” of the trampoline, a single mesh with 2 bones in it, is completely corrupted on mobile devices, appearing 20 feet above it’s normal location and stretched out in a very unusual way.

You can find the place where this bug happens here

If you look up into the sky, on mobile, you will see the first trampoline has it’s entire surface floating distorted high up into the sky.
This has a 100% chance of happening to everyone on mobile who has attempted it so far!

This is a very random bug that is potentially about to ruin the launch of the next update to my large roblox game.

This is genuinely game-breaking, and I can’t figured out what went wrong. I thought it could be my fault, but if it interacts differently on mobile than on PC, it’s clearly a bug of some description. Any staff help would be appreciated!

edit: No scripts are being used, I said I animate it, but all scripts have been removed for testing purposes. This is purely a model/rig bug.


Has anyone else experienced this sort of thing? I’ve never seen any bug even remotely similar to this before, so anyone who has seen mobile-specific rigged mesh problems, feel free to reply what you’ve seen

Hello, Is your trampoline model grouped?

The meshpart is in a group/model, yes

Hello, is your problem still relevant?

Yes. I’ve had to completely remove the bones from my model and leave it un-animated for the time being.

You can go to the linked place on Mobile and see the missing trampoline piece for yourself, most likely, to confirm

Has anyone else experienced an issue like this? I’ve found trouble finding anyone who has, but this bug is basically experienced at a 100% rate for me once it’s popped up.

Hi, could you please provide a repro file and instructions with how to reproduce the issue? Thanks!
