[BUG] `/mm spawners copy` has a pointer/data issue #6421

Copying a spawner and changing its mob type will change the mob type of the first spawner. This can be reproduced 100% of the time for me with the steps below. Restarting resolves the issue.

Assume MobSpawner1 has MobType 1.

My steps: Create your first spawner. /mm spawners copy MobSpawner1 MobSpawner2 /mm spawners set MobSpawner1 mob_type MobType2 /mm mobs kill MobType1

Result MobType2 will spawn at both MobSpawner1 and MobSpawner2.

Restarting fixes the issue. This only happens in runtime.
