As part of the parse avoidance feature, emake attempted to read a parse result file, but found some other type of file instead.
You may have experienced disk corruption that changed the file header.
Or the indicated file may have been replaced by another file, not by emake but through the action of some other software or operator.
Check for other signs of disk corruption. Run disk-checking software.
Examine your processes to see if you try to edit the cache, either
manually or through some automated process. In general, you may safely
move the entire asset directory to a new location, delete it entirely,
delete just its
cache.* subdirectory, or use emake on it. Other uses
of the asset directory are not supported.
