Colouring of particle tracks with multiple files loaded
When multiple results files are loaded, containing the same named particle tracks, colouring of the tracks by a particle track variable can fail, and make particles unusable for visualization after that point.
This is due to a coding error.
One workaround is to use right-click to colour the tracks. Alternatively, you can set up your track plots without colouring them, and then add variable colouring at the end. However, the only complete workaround is to ensure that particles names are unique across loaded files.
