VCV QNT: Anyone seen strange behavior loading a patch with multiple QNTs?

Windows 10 and 11 here, VCV Pro 2.6.4.

I have a patch with 4 QNT modules; when I loaded the patch today, I noticed some of the QNTs had a different selection of notes than I saved them with, but I couldn’t change the note selection by clicking on the module (or ctrl-I or ctrl-R). Making a new QNT in this patch results in an unresponsive module with all notes selected AND active (bright yellow). Seems I can load a selection containing QNT modules and they act as expected…

I filed a bug report, but was curious if this was just a one-off-specifically-corrupted-patch (cosmic rays!) or if anyone else had experienced something like this.

Perhaps related to this known bug in VCV 2.6.4?
