Draconic Resilience Multiclassing Bug on Test
It looks like the character management changes on test do not respect multiclassing for Draconic Sorcerers. On Test it adds a hit point increase at every level regardless of class, however the class feature specifies that the bonus hit point is only granted whenever a sorcerer level is gained.
The can be reproduced by creating a new character in a fresh campaign with only the PHB loaded by adding a single sorcerer level and then a single paladin level. The character will have 14 maximum hit points (gaining 7 from each level), however they should have 13: 6 from maximum gained at first level as a sorcerer, 1 from Draconic Resilience, and then 6 from the level gained as a paladin.
