Found a new possible issue with the patch. Just after passing the named spider (Arachne) you enter that flesh area. When you do you get a small dialog cut scene and when done you are stuck on the rope that you descended on. Can't move at all.
Tried multiple times with same result. Loaded the save in 1.2 and was able to bypass.
Hope that makes sense.
I know what part you're talking about, I'll check it out. Not sure what could be causing it, hopefully, it's something obvious. Thanks again for reporting all the bugs.
Edit: I went over the files in the js and data folders and nothing stood out between them that would affect the event. I tested the event in v1.3 five times total, it worked fine the first two times, but when I used the control key to skip through the dialog it froze, but then I tried it twice more by skipping the dialog and it didn't. I think it might be a problem with the game itself, possibly the autosave feature, maybe the nw.js needs to be updated or downgraded? I'll look into it a little more, but I don't think there's much I can do.
Edit: I replayed the event on v1.20 and I got the bug after repeating the event six times, so it seems to be a random occurrence that can happen on both versions, it happened on the sixth time when using the control key to skip through dialog, however, I have no clue what could be causing it to occur or how to fix it.
Edit: After testing it a bit more on both versions, it seems to be somewhat random but using the control key to speed through dialog does seem to increase the chance of becoming stuck. For you to get stuck multiple times consistently on v1.30 is concerning though if you want you can send me a save file near that point I can look into it, but other than that there's not much I can do for anyone else who runs into this problem.
