the plugin works well but I had to modify it on one point, when a home is created, it doesn't save directly, it only saves when onDisable is called except that when a server crashes, the method isn't called so homes are lost, I solved this by adding saveHomes() in the addHome and removeHome methods.
Yeah sorry, it's implemented wrong. The way it should work is saving each home async to file while its updates, with an ReentrantLock. I want to fix it really, but it's hard to me to find time/motivation for it sadly.
