Just experienced the same issue.
Hi, please send me some screenshots of the places you're seeing this issue in a tumblr ask at https://bladeweaver-if.tumblr.com/?source=share
I've looked all over for instances where this happened but it seems I still haven't found them all, so having some idea of where I've gone wrong would be a big help!
I’m sorry but I only kept my save from the end of the demo. I loaded it up and went back as far as I could go, and unfortunately I can’t seem to go back any further than Gwyndon’s arrival to the prep-room.
The scene where this issue was most notable for me was shortly before this when Sonia was gearing up. There were only several instances throughout the whole story prior to this; where it seemed to swap them in a singular mention, but for this gearing up scene a page or two of text swapped Sonia for Callen entirely.
Oddly enough, theflightlessone mentions Callen being given she/her pronouns but I don’t remember that happening for me.
Maybe I’ll try to speed through and see if I can replicate it.
Edit: I sped through again and was able to reproduce it and take pictures. I’m not familiar with tumblr though and am unsure where to send them.
That's alright. Just click this link Bladeweaver and click the 'Ask me anything' button. You should be able to simply upload the images there where I'll be able to see them. You could also DM me if you make an account :)
I believe I fixed the instance where Callen had the wrong pronouns (you go girl?) in a previous patch so that'll be why you aren't seeing that, though I'm now looking at the other places you've mentioned.
