I went thru that stage but it was caused by the software infill / wall overlap defaulting to 30 by Creality design even though their own highlight notes 15 should be the default. (Bambu has 15)
At 30 it caused the nozzle to bulldoze the filament thereby pushing the item over.
Changed to 15 and it never happened again.
AND they still have not changed it to default to 15

Yes I know it says 20, just testing
