Thanks for telling me! I did release a patch earlier, but maybe I accidentally added the incorrect file that wasn't my patches for some of the glitches you found...
1 - I found that one earlier and patched it!
2 - Not sure how you got screen soft locked in black as I didn't have that issue nor did he disappear for me. Now I did find the crystal sticking around and fixed that! As a little bonus while trying to figure out what the black screen and disappearance was about, I did find that I had the event end too early which stopped you from getting his nude costume (Which I added the debug crystal)!
3 - I think I found the grass you were referring too (hopefully)
4 - I fixed the issue with the repeats!
5 - I fixed the fish crate (I accidentally had it check if it was done with the carrot crate event)
6 - I found the snake girl and moved them to a spot where you can reach them!
7 - I fixed that with 1 since I also noticed that.
By the time you see this I will have started to upload the fixes! Thank you as always again for telling me about these as I did miss quite a few!
