with 'beast girl' you mean the two Neifu girls? Im playing on 3.24b version. I dont have that girl on my team rn, shes a must to this part of the story?
I mean the dog clan queen girl (in your pic), her name's Gin, I think
gabe said that she had fixed it with a more recent version, by not allowing you to do the event (fighting against gin, and then...) involving the decision to let gin go (WIP as far as I tell, as game is not complete, lol: choosing this "good" choice bypsses the cut-scene getting frozen, as she's not a slave when you take over castle warrenguard: going through fierra falls, killing the tree-ent mini-boss, with the cut-scene as you enter through its prison) or not (she becomes a slave of yours at castle warrenguard, but this caused the frozen screen if you done this first before: keep reading to the right), until after you taken over castle warren guard (gone through fierra falls, fought the ent tree mini-boss, etc), if (and it seems it has for you) it does still persist...
hopefully, you got a save before you fought gin and made the decision to keep her as a slave
as to avoid the frozen cut-scene:
1. never fight gin, until after you've taken over castle warrenguard (got past its dungeon cut-scene)
2. fight gin, but choose the "good" choice of letting her go (NOT taking her as a slave)
3. waited on fighting gin, doing the castle warrenguard sewer cut-scene first, and then you can go back and fight gin, and choose whichever option
----------
if memory serves, you don't get her on your team (though I've not played the most recent version), she's only a slave (if you've chosen the "evil" choice after you fought her), but maybe you do (don't remember it being so, and maybe in most recent version or in future plans / game progress, you will, when/as game works more on the main story)
