Unknownreported this bug
Summary
When attempting to spawn any mythicmob using an egg from a dispenser, if there is only a single egg left in the dispenser, it will continuously spawn that mob. If there are more than 1 egg, it will reduce with each spawn as it should, but once it reaches that last egg it is infinite.
Steps to reproduce
Place mythic eggs into a dispenser and repeatedly fire it
Current behavior
The last egg will always continue to spawn the mob instead of consuming
Intended correct behavior
Consume the final egg as normal
