In the weird bugs department: On an ExFAT/MBR formatted drive if the filepath to a track has a folder whose name ends with a dot the Prime 4 will report the track as “failed to load” However Engine Prime will load that same track from the same drive just fine.
/Music/the tracks./thetrack.mp3 will fail to load
/Music/the tracks/thetrack.mp3 will load fine
This bug was confirmed after investigating it with MixMasterG of the ATGR Production Team and is fully reproducible. It’s unclear if there are other characters besides the dot that will cause the same issue.
