I ran into a crash while ago related to that mod but didn't realize it was an interaction with B&S.

From my testing, the crash only happens when running B&S, More Monster Girls, HAR, and PerformanceFish (and their dependencies) at the same time. Removing any of the four mods resolves the crashing.

Removing PerformanceFish+Fishery seems to be the most informative, as I am able to get the game to load up but get several errors on startup:

With PerformanceFish added back in, the game crashes before it gets to the main menu screen. Player.log looks like this: https://gist.github.com/AeAstralis/fad826609a30ffafe62a322854caefca

"System.ArgumentException: Field alienRace defined on type AlienRace.ThingDef_AlienRace is not a field on the target object which is of type Verse.ThingDef."

Figures...

Probably the Monster Girl mod is not converting their races to HAR races when HAR is active. This will cause HAR-errors later down the line (or at least have such edge cases) without my mod if e.g. tattoos are put on them, etc.

Imo. this is either on Erdelf (HAR author) or the Author of the Monster Girl Mod.

Either Erdelf makes non-"AlienRace.ThingDef_AlienRace" be supported so I don't have to convert my races when HAR is active.

...or the Monster Girl race needs to add HAR compatibility.

Imo. Erdefl should just support non-HAR humanlike ThingDefs.
