I don't know how many other people were getting this issue but I finally found the cause of one of my own problems.

When running L&L's Create Race List exe under Windows XP, the exe would suddenly freeze after the line "Tes3a^:)".

Finally found out the cause of the error. Slof's BB neck fix.esp.

I went through a 150 mod list to find that one esp. xD But I found it! I thought I would post this in case it may help others with the same problem. I don't think it was ever reported what caused the freeze.

For now I can just use Mash to take the esp out of the cello save file to bypass the problem. Anyway I hope this helps someone.

Edit: Partners Unlimited doesn't seem to work well with the Create Mesh List exe.

Is that for Khajiit and Argonians? If so, I'd leave it out when creating the meshes. The mod doesn't work with beast races, so it's best to leave any that affect them out when creating the meshes.

Well, the BB neck fix fixes a mismatch neck issue with one of Slof's better beasts esps (i'm pretty sure its Slof's Better Beasts a.esp that needs it). It only affects Argonians. The BB neck fix is a patch esp, but the main esp goes through the Create Race list just fine.

Also, apparently Hold It and Partners Ultimate don't like to be put through the Create Mesh List exe. Causes the exe to crash in xp. So Slof's BB neck fix, Hold It, and Partners Ultimate need to be unchecked in Cello.ess in order for the exes to work. At least, those are the only mods in my list that cause any problems.
