Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2-dev build 5c547ea

Operating System (OS)

Windows

OS Version

windows 11 Pro

Additional system information

I have ERCF v2 & at the first color change the printer changes color but never resumes the print. In build 2.3.2-dev build ad0ed95 everything works as expected. Also in 2.3.2-dev build 5c547ea the skirt doesn't go around the prime tower causing the prime tower to print on top of the skirt. When this happens my printer is froze up, even the emergency stop doesn't respond I have to turn the power off.

Printer

Micron+ 180 w/ERCF v2

How to reproduce

Just slice a multi color print.

Actual results

Expected results

Print should continue.
