After clicking create in constraints, then hinge and selected the both part, studio glitched and this behavior happened. At the time i’m unable to click on items to select thems and unable to move the parent via explorer.
It might be a momentary glitch in your Studio. Sometimes it happens.
Save the game, close out of Studio and restart it to see if that helps.
Try the exact same procedure (selecting the attachment and the model then dragging it) to see if it happens every time. If it doesn’t then you shouldn’t have to worry about it. If the bug happens again then you should report it.
Did you have both the model and the constraint selected inside the model when you dragged it Wind Turbines folder? If you did then it may have tried to parent the Attachment and the Model.
Hi @MagicLuau, could you provide a minimal rbxl file and steps to reproduce this issue? From the current video and description it’s not easy to tell what exactly has led up to the error. And as was pointed out by Scottifly, the message usually pops up when trying to re-parent an attachment to a non-basepart or attachment, regardless of any other selections, constraints, etc and is completely expected as a current limitation of attachment use cases.
