A friend and I keep getting kicked to homeworld when joining an instance of ReikiBeach and other similar worlds with this error message. is this common for this world type and all subsequent clones uploaded?
this world as a prime issue
This is an error with the world, and is not something you can solve as a user! The person who made the world needs to fix it.
The world probably has either invalid IDs (out of allowed range) or duplicate IDs that the creator needs to address with the network ID tools in the SDK.
If you can get the output logs that would be very helpful.
