I have the exact same problem on my main save, i am softlock from gin's quest as well, the only way i found to fix it was to restart a new game... hopefully it will be patched later on
Ps, I suppose the bug is linked to the final scene of gin's quest as it require the presence of cassie by the forest pound and it might conflict with pregnant events, so i doublt it will do the same wight the bandit gril as there is no sutch requirments
