Checked both occasions on a fresh play-through and it didn't have an error. And yeah, the new version doesn't really work well with the older saves bcs there are lots of changes behind-the-scene :x
I don't know why the older version works for me and not the new one. I just started playing it yesterday, so I didn't have any older saves I was loading, just the saves I did yesterday before the glitch occurred. I'm glad the older version works for me though. Thank you!
