Some "bugs" from my recent games:
MTH relation display
I have used Shipyarding stratagem like 3-5 in a row:

Unit feats for special infantry
Currently you can add feats to minor units (Subculture specific, Free Folks, Xenos) however the feats are removed after new turn. I understand it is weird to add for example Anima Priest to Xenos but for humans is should be possible. Do you consider expanding upgrades for this types of units so they can catch up with Militia or standard Troops?
Air strike additional info
Could you please expand a tooltip when making air strikes? For now, it is hard to manage units if you have multiple models in same category - they mostly look the same. I often use like 2-4 light aircraft models

Air units feats (Battle Group) 1.25d
Hard to say If it is a bug or intentional but it is possible to attach feats to air units
