No- I'm puzzled!
Tried to make a simple plan - could not replicate the issue.
Went back to my plan I'm working on - Figured if I deleted everything (all Furniture etc.), it might be small enough to be 'simple'
Used the 'Delete Objects' off of the Edit from the main menu- deleted every thing except the Cabinets
Can't replicate the issue.
Kind of good news / bad news. Good news is I found a work around. Bad news is I have no idea why it happened,
Kept a back up (obviously) - so now I'll apply my adjustments - then copy/paste every thing back
Thanks for you help. (I guess)
