Hello! I have a suggestion. You should make the "TNT/Creeper" explosion chance different. For example, I want TNT to have a 30% chance of dropping the spawner, and I want Creepers to have a 50% chance of dropping the spawner. Thanks :)

Migrated from https://dev.bukkit.org/projects/silkspawners/issues/99

Any news about this enhancement? :) Looking forward to it

A month passed by, is there any info?

Nope, currently I'm not having much spare time.
Feel free to make a PR, this would be appreciated.
