Arelith

Selecting Yuan-ti Pureblood gives you +2 intelligence, as intended, but does not seem to relevel the character to grant the appropriate number of 1st-level skillpoints (as it does when choosing the +2 Intelligence gift, or when creating drow or characters of other races that gain bonus Intelligence).

A fix is in the pipeline.

The fix should be live, though a remake may be required to get the extra 3 skill points.
