It came to my attention that Improved Familiar selection of Psuedodragon was not manifesting correctly. After some investigation, it appears the PREREQ evaluation for the ALIGN is not checked when the alignment is changed. Forcing a check requires altering the PC level.
I have changed the check from inclusion to exclusion to avoid user issues. But wanted to raise this issue for consideration when a coder has an opportunity to evaluate the push/pull system.
NOT required for 6.4.1 release.
