It would be helpful for those of us who wish to keep things complete if the logs could show the folder or parent it was trying to locate, for example:

ridhero/srom, ridhero/prom, ridhero/crom0, ridhero/m1rom, ridhero/vroma0, shocktr2/srom, shocktr2/prom, cshocktr2/rom0, shocktr2/m1rom, shocktr2/vroma0
