Yeah, I did, it would still constantly be 2 hit points below whatever it should have been. On another note - during the installation I installed BGT Tweakpack, and changed my mind, uninstalling all parts and deleting the BGT tweakpack .tp2 file/install file. Reinstalling it a third time seems to have fixed it, but only sort of; importing a character sets the base HP to zero, but at least the calculations are correct. I've also noticed that exporting a character with a familiar has some unforseen consequences (tons of free HP). Is there any way that it could be coded to not transfer the extra HP and still allow you to summon another familiar?
Oh right, so my question was could installing/uninstalling the tweakpack have caused that problem.
