I have Minepacks on 3 servers. On two of them I am using the same MYSQL database and have bungee set to true. On 1 of them I have MYSQL database set to a different database and use bungee set to false. However all three servers are still sharing the same backpack. Do I have to remove the use of MYSQL to stop this on the one server I do not want it sharing with?

Sounds like you have set the same database on all 3 servers. As long as they use the same database, they will share the backpack.

I double checked because that is what I thought at first also but it is not. Now I do have other plugins that are all using the same database but not this one.

I will keep an eye on it but seems to be working now like it should. Only thing I can think of is I thought I went to other server when I did not because I have not changed anything with files except for adding online to one of the MYSQL files where it said to match what bungee is set at. Maybe that did it.
