Hello, just to provide another update so you're not in the dark. I'm getting close to finished with this update, I'm currently running tests to ensure everything is working as intended. I'm hoping to have this finished up late tonight (EST time zone) or by tomorrow night at the latest. So far everything seems to be working well.
On a side note the plugin which will need to be updated on your end is the Ultimate Event Spawner plugin, the boundary system code remains the same after this update. All the code is done within the spawner since this is a spawner related update.
I'll post here to let you know when the spawner update is ready to be downloaded.
Thank you for your patience! I know it's been a bit of an extended wait.
