Currently entering pregenerated characters (as available on the Paizo website, free download). When entering both Druid and Ranger pregens, the animal companions are not scaling from small to medium (no option given). Medium animals are available, but as they are not "companions" their abilities are not the same. All abilities are correct as animal companions, etc, but size is still small. Specific pregens that are affected: Ranger level 7, Druid levels 4 & 7.
We can assume that all such classes with animal companions are probably affected.
James, please reopen the character and view the character sheet, NOT the character summary. You will find that "Biter" is, indeed, a medium creature.
Never mind. I use the sheets dynamically, and rarely print them out if I have my laptop, so I was unaware of the correction for the printed sheet. They are listed as small until you print the sheet out.
Thanks for the clarification.
