0.7.1 Traits modifying stats creatures have not working as intended

Master of familiars trait was giving a very small amount of int for casts which led me to some testing.
After some research it seems like any ability that makes creatures have “More intelligence” including annex and master of familiars and stat boosts from artifacts stack additively with each other which makes them very underwhelming. For instance, raven acolyte gives the same amount of stat as half of an int gem, which usually results in a 3-5%ish boost. while ‘morph sorcery’ tends to give about a 50-70% boost.
Not sure if this is a bug or intended, but i did a bunch of research so i wanted to at least bring it up
