If you weld something to another part and then set the weld’s enabled property to false, once you publish the game or restart studio it’ll just re-enable itself. Another strange thing is if you play test it works just fine. Is this a bug???
edit: the only way i could solve this issue was copying a previously created weld that was disabled and pasting it into the part and setting part0 and part1 accordingly.
Neither, I found out this is a known bug yet to be fixed, I still run into the issue sometimes. I found just restarting studio and re-applying the welds a few times fixes it. Or copy and pasting welds that are already disabled into another part prevents it.
