[mennucc]

Cura Version

5.6.0

Operating System

Linux (Ubuntu 22.04)

Printer

Ender 3 Pro

Reproduction steps

• open Cura
• load multiple pieces
• move them so as to arrange them on the build plate
• save project file (3MF) file
• close Cura
• open Cura
• load project file

Actual results

result: the positions of the pieces are randomized

(sometimes some of them are so far away from the build-plate that it is difficult to find them)

Expected results

the pieces should be in the same positions as when I saved the project
