[Every Creative] Weird plot bug..?

So I came back on my computer and checked skype, @CoolWhip342 sent me a message asking why I removed everyone from my plot. So I went to creative3 and checked and saw this.
I had almost 20 people added to my plot and none we're added anymore. So I was so confused and decided to check other plots to make sure it wasn't just me. Turns out, it wasn't just me..
These are all plots I was all added from and there was a lot more people added. These we're from creative3, now let me show you creative 1 and 2.

Creative2
I never removed anyone from my plots and the ones that aren't mine I remember being added to it. They said they never removed me aswell. I wasn't added to Kick's plot but I showed it because there we're many people added and suddenly, all removed and undenied. I don't know if It's for every single plots but it affected me and my friends.

 

I think it's when the server restarts it also removes the added and kicked persons.

 

I noticed it yesterday but didn't report it. Also, I experienced many restarts and this never happened before.

 

Some people said it happens between reloads, or restarts. I'm not sure myself. I can't really test it. It might be the /reload. Since, you would reload all your server files to load for example, new plugins. I hope they find a way to fix this bug though.

 

Just noticed something, it might have something to do from when creative 1 2 and 3 we're down?

 

I believe it was a setback from when the servers were down.
