I believe you
@Briscoex, and I'm sorry that you lost your mythical razorpine. It sounds like you've accidentally started the critter glitch which happens when you by swap bait/critters with an item in your inventory, save, swap them back, save. Then when you use the item, it sometimes spawns the bait/critter, and sometimes it can just consume the item into nothing.
Hopefully, you've taken advantage of the extra save slots and manually made backups of the character before it lost the razorpine, explained here:

You can also let 505 Games know of the bug directly here:

Mobile will be getting a big update later this year that should hopefully fix this and other issues.
