Steps to Reproduce the Bug

1. Have a limited spawns amount active, like 10 for example
2. Put an egg inside and wait till the spawner expires
3. Put a new egg inside
4. Use the spawner key to access the settings, set it back to on and click save,
5. The spawner will not turn back on, but the new egg will vanish.

I think instead of making the new egg vanish it should just either not allow you to put an egg into an expired spawner or drop the egg right back out when attempting to turn it on.
