I'd like to confirm that I had no issue with the forest in the beginning. I personally really hated that glitch because the first time I played I didn't read the front page properly and had not saved my game very recently. I also found a strange glitch where a non-violent Chef appears over one of the crates if you go in and out of the shipyard building enough.
I would also like to say that I really enjoy this hack and just recently got back into playing hacks and found I had lost my previous data and there was a new version anyway so I downloaded that. If you do quit this hack it would be sad but it would be understandable and I think it's fine for what it is as it is.
Well here's something interesting. The medical kit makes most of the screen darken and it works continuous so if you do it enough times you can get a black screen. Theres no need to fix this and it isn't harmful to the ROM at all. I just thought I'd show you.
