Filament always gets stuck in Nextruder on retraction—but only filament 5
I've got an MMU3 with a MK4S. Filament 5 keeps getting stuck when being extracted from the Nextruder. I have no clue why this happens. I just cleaned the MMU3 itself so there is no debris in there.
I just finished the simple 5 color test ring and everything went smoothly. I then tried something harder like the 5 color benchy. Every time color 5 unloads, it gets stuck in the Nextruder—but only color 5. All the filaments are the same material, age, and brand. (Granted it's a cheap brand.)
Why would only color 5 get stuck?

I use a loading fork/guide in the buffer and have on occasion forgotten to remove it after loading. Could it be something this simple?
If not, I’d suspect a restriction between the MMU and the buffer on #5. Also check the set screw on the drive spur in the MMU #5.
