Say I found a seed which contains an item I just unlocked, right in the first item room. What happens when a new player, who hasn't unlocked that item, plays my seed? I would guess one of the following situations would happen:
- The 'locked' item will be substituted by an item that isn't locked for the new player;
- All the items in the seed will be different, because the new player has a different item pool;
- The entire run will be different, including the rooms and such (RNG will derail);
- Nothing is different, the new player can obtain the item that is actually still locked.
Has someone tested which of these cases happens?
