MMU can't change extruder when Split to Objects is used in PS2.5.

[mrjackson]

Description of the bug

After splitting a multi-part object into separate objects, changing the extruder doesn't work properly for all objects. The List updates but the object itself does not.

This did work as expected in 2.4 prior to upgrading to 2.5.

Project file & How to reproduce

WireBolt.zip

1. Open new project (With MMU2 setup).
2. Import multi-part 3MF (exported from Fusion360).
3. Click YES for multi-part detected.
4. Select object and click "Split to Objects".
5. Select each object and change the extruder.
6. Object does not change color in the preview, but does in the part list. If you change all objects to the same extruder, the purge tower remains.

Thanks for your report. I can reproduce this bug from PS 2.4.0

Hi, I test it in the upcoming 2.6.0, and the issue should be fixed. Object color renders according to set extruder after a split. Thanks
I am closing this issue.
