weird. the items works fine by me, and the bastes removal are probably just not released yet so when creator adds the defeat scenes from those bastes, he will probably also add the place or method to remove them.
also I noticed the rescue mechanic has also a fun minor bug, if Alumina/Alumines gets captured, after you rescue her, the enemies wont target her anymore, they will only attack Tangel, however, if tangel is the one captured, after you rescue her the enemies attack both of them as usual, I also tried tangel getting captured after rescuing Alumina to see if she were alone they would attack her, but they still attack tangel and her sprites appear even tho shes supposed to be captured.
so basically whenever you get Alumina captured and then rescued she will become invincible, no matter when or how you do it you will get an untargetable character that uses the other as an infinite tank and you will be able to win every battle in any difficulty lol (poor tangel)
