Are you using Accessory? If so, try changing some of the grip properties. If not, your method might be deprecated, and you need to switch over to Accessory.
Yes, all of these are accessories. I used a plugin to import them from the catalog. When I logged on to studio today, they were all normal, but whenever I cut and paste or modify them, they go back to their initial, glitched state.
Running the game fixes them.
When I copy and paste them from the running game, they fix but then revert back to their glitched state.
Apparently they only fix when the game is running.
