Bug Description

When starting a multicolor print with more than one plate in the G-code file, the printer assigns the wrong filament color to one of the colors.

This issue happens with any print that contains more than one plate in the G-code file. It affects both single-color and multicolor prints. In multicolor prints, the first color is selected correctly, but another color may be assigned incorrectly.

I closed and reopened my browser, and it seems to be behaving properly now. It is selecting the correct colors in v0.2.3b3.

I will keep an eye on it, and if the issue happens again, I will report it here.
