I have seen the same when putting all original VM files needed into /templates/mytpl/html to develop overrides without changing anything at the moment.
Not being shure but, it looked like something in relation to manufacturer and / or price, couldn't identify file(s) being related. Tried to identify reason with removing one file after the next as well. Removing all VM files being copied "Array" vanished. Must begin at step 0 again when time permits.
Maybe there is a problem between component and mods. Getting absolut different paths when calling manufacturer page via mod and calling via component is another symptom. This problem is already mentioned in another thread.
Template being used for developing is Protostar. As long as original files from VM are in */html everything should work fine but, it doesn't. There is some hardcoding as well.
