Thank you for reporting this! I believe something from the new update messed this up, as this didn't happen in the old versions (and my playtesters also tried the items on everything), must've been the unfinished language-switching code. I shall look into it!
Solved it! Turns out that, for this exact door (and maybe others??) its saved as "unlocked" once you enter the room, which is why it didnt save when you just used the objects. I shall upload a new version and fix all the other doors. Thank you again for reporting this!
