I'm a first time player/tester, and I started with the v19 patch and Scenario 1.
I finally completed it, and it seems to get stuck at the very end, after the credits, when Benetram starts to speak with "How ghastly".
I tried to reload/restart, try different settings, but it always freezes there. You can still see the animation of Benetram blinking, but nothing else happens and you can't proceed, or do a complete save.
I loaded the same save file into a vanilla USA copy of Scenario 1, and I was able to get past the post-credits sequence and complete the save. I did notice some of the text is different, and I'm curious what the patched post-credits sequence reads like. Are there any differences? I could try burning a copy of the v18 patch, if y'all think that's worth testing as a comparison.
