I have created some hand-made mipmaps for a texture. Loading up the EGG file the first time works just fine and I can see the different mipmap levels, but loading again (where the EGG is being read from BAM cache) results in an error and the texture is not loaded:

Looks like it is actually trying to find a file with the # symbol in it instead of swapping it for the mipmap level?
This is the texture entry in the EGG file for reference:
