Bug #2:
CPP and Project Q replace default higher-resolution heads with lower-resolution heads.
The CPP does this for pfa0_head007, pfd0_head006, pfd0_head007, pfd0_head010, pfg0_head001 and pfg0_head002-008.
Project Q does this for pmh0_head002.

Fixing this depends on how meticulous you want to be. The simplest way of course would be to delete these plt files from the CPP and Project Q. But both the CPP and Project Q are attempting to replace the default head textures with colorized versions (with eyes, lips and eyebrows using tattoo and hair colors), so a better way would be to replace all these files with higher-definition colorized versions. Such things do exist. The "Realms of Mythology Heads" collection on the Vault contains colorized versions of pfg0_head001.plt and pmh0_head002.plt, and their use of color channels is consistent: tattoo 1 for eyes and tattoo 2 for lips.

And the JenX collection contains good-resolution colorized versions of all of these heads, although their use of color channels is less consistent:

Now, I'll digress for a moment to describe the special case of human male head #143 (if you're bored by my wall of text, skip this part). As far as I can see, it's the only head in the game with no good-resolution version available in the texture packs. We could say this is a bug in the game itself, an oversight by Bioware. Currently the CPP replaces it with a colorized bad-resolution version and Project Q doesn't replace it with anything. There's a higher-definition reskin by Yavel on the Vault:

The game data contains models for both phenotypes, pmh0_head143.mdl and pmh2_head143.mdl, both of which use the texture pmh0_head143.plt. Yavel's reskin contains pmh0_head143.mdl in addition to the texture file, but the mdl file is identical to the unmodified version. And as for the plt file, there's a colorized version of Yavel's reskin available here:

Yavel's reskin:
The eyes on the reskin could use some adjusting, to make their position on the plt better match their position on the mdl or vice versa, but it's still a clear improvement over the original.
