These are some problems that I have experienced during games:
-Sorceror Lord Spell: Spiteful Tutelary (3rd Spell for Summoner variant) sometimes doesn't manifest only leaving scorched ground
-Sorceror Lord Spell: Malificio Pavoni (3rd Spell for Warlock Variant) sometimes leaves a singular member of a squad invulnerable and immobile after the initial explosion and stun until used again on them
-The Range/Melee stance change does not appear on the Ferrum Infernus Dreadnought, however it appears and is usable if it is selected in a group with multiple Dreadnoughts
-The Lord of Change consumes about 5 pop (not sure if this is intentional though, if so my sincere apologies)
