I don’t really like advertising my own plugins too much and I hope @HassanS6000 doesn’t mind but since you’re having troubles with Gravestone and I made a plugin a while back which is very similar(actually inspired by a similar mod). It’s called HISYS aka Hey I Stored Your Stuff (yes I’m terrible at names 
) and should work with all protection plugins, if not then tell me and I’ll get it fixed asap. I haven’t gotten to work on it in quite a few months but it should still work on api 5.1.0, if not, I plan on getting back to work on it in a few days anyways.
