I have had a problem several times now with Tinkercad: When part way through a project, I am suddenly unable to make any further changes - every time I move a component, it jumps back to where it came from.
I haven't touched anything to my knowledge, is this a glitch, or does anyone have any ideas what is happening?
(BTW, I have discovered that cutting and pasting the work into a new design fixes the problem)
Thanks
Phil
