Bug Fixed

This bugfix release resolves a server-side compatibility issue that could prevent unmodded clients from joining servers running Spawner Fix.


What was the bug?

Previous versions registered a custom command argument type for the spawner gamerules. On dedicated servers, Minecraft sends command registry data to connecting clients. Clients without the mod did not know this custom registry entry, which could cause a disconnect with a registry mismatch error.


The Fix

  • Server-Side Join Fix: Unmodded clients can now join servers running Spawner Fix without registry mismatch disconnects.

  • Vanilla Command Arguments: Replaced the custom gamerule argument type with Minecraft's standard integer argument handling.

  • Safe Client Sync: Optional clientbound sync packets are now only sent to clients that support the Spawner Fix channels.

  • Spawner Range Behavior: Spawner activation range remains configurable and defaults to 128 blocks, matching normal mob spawning distance.
