When dyes are used in an inexistent recipe and one is removed manually, the other will stay for the rest of that session.

Steps to Recreate

1. Put two dyes that don't mix into the inventory crafting slots.
2. Remove one.
3. Try to remove the other one. It won't work.
4. Try placing down a crafting table. It will work there, but the inventory crafting slots will remain blocked.
5. Try dying(killing yourself). It won't work.
6. Try dying(adding a dyable material) it won't work and the output won't come out.
