I accidentally made a "Small Construction Provision" while my quest only asks for Normal and Large variants of them.
And i simply cannot get rid of it from my star menu there is no small x at the top right.
To add to that there are far more items in the star menu that cannot be deleted, a ton of buffs like 'Stadium Snack' 'Oujia Board' 'Rain of Arrows' 'Weapon Boost' etc. all cannot be removed. It's strange how random it is to be honest.
