[1.7.3] Crystalline Set + Mana Coil

[Erenion]

When the two Crystalline items are worn together, the weapon gains a 10% chance to cast Manathrust on spell hit.
If you make a staff as the weapon, put a mana coil on it and then complete the set, everything works just fine at first.
When the set is broken, however, both the Manathrust from the set and the Lightning from the Mana Coil will be lost.

Also, taking off the Mana Coil in this state will cause an error and delete said tinker.
Recompleting the set will not restore the Lightning, but it will allow the Mana Coil to be taken off without issues.
Destroying the staff or armor will also delete any tinkers attached to them.
