I'm building a 1992 tube stock replica, and whenever I press 'undo' the whole build teleports a little to the right/leftof where it was before. This is really annoying as I have to load another built then re-load the thing i'm making to fix it back on top of the circle (the one in the default designer, you know it)
You have a small part a far distance away from the build, look for it then delete the part, painting most of the build a bright green will help with finding the part
@Gestour Right, I do save often but also hit undo often
Never hit undo.
I suggest saving often, and reloading the last save instead of undo.
Just load the build into the simulation, then exit back to the designer.
That fixes the issue.
