What steps will reproduce the problem?

The mobs sometimes don't spawn my spawners. I need to replace the spawner so mobs can spawn. Sometimes I need to change the difficulty to 1 even when it is set to 1 to work. I don't know whats going on. The 'when' is undefined

Expected output

Mobs spawn always
