[PS 2.6.0 A2] crashes when generating gcode for sequential printing

[Ohmarinus]

Description of the bug

Sequential printing turned on with standard settings.

3 small objects spaced out across the bed.

Crashes when generating gcode (at 90%).

Doesn't crash when generating gcode for the same object with sequential printing turned off.

Project file & How to reproduce

sequential_crash_PS2.6.0_A2.zip

I turned on sequential printing with the standard settings.

Pressed generate gcode and then it goes to 90% and after that it crashes PS to exit. It's a rather simple error.

I also noticed that the third object that I copied using the add instance + button has a wrong outline:

Thanks for clarifying, I only search for the term 'sequential' before submitting the bug, it appears you're right and these crashes are related.

Fixed in 2.6.0-alpha3. Closing.
