Hey man, I just recently bought Cave Story+ on steam and it was fantastic! I discovered your 4th ending mod, which i successfully installed in the game with plus-porter 220.127.116.11 and am currently playing that mod as we speak. While going over the challenges that were unlocked when beating the normal game with the 3rd ending however, it seems as i tried to open the blood-stained sanutuary time attack tab from the challenges menu, it took me to the level alright, except my character dissappared entirely, showed the drowning counter about 20 sec later then died to restart to the menu all over again. It's weird because once i uninstalled the game and reinstalled without your mod, the time attack for sanctuary worked without the appearance of the disappearing/drowning bug and could play it normally. My question to you is has this bug ever happen to you or to anyone while playing that challenge mode without the 4th ending mod or is it just me? Thanks again for your awesome mod and cannot wait for more mods from you in the future.
