DrawIT Saving Error

[httpsRevenant]

The plugin before the error works perfectly, after the error everything starts to fail.

When starting the creation of the arena everything works fine until it's time to save. I place the lobby, the spawn drawer, the board positions, the save interface opens, I modify the number of players, I click enable, and when I click "Save", it throws an error on the console, this:

[21:19:23] [Server thread/INFO]: Revenant issued server command: /DrawIt Save

I checked the error and focused on the line Caused by: java.lang.NumberFormatException: For input string: "0,5" and the only thing with a value of 0,5 is the coordinates of the arena lobby and the point from the drawer, so I reinstalled everything again and tried to set the sand to a point without a decimal, but the same thing happened.

As I said at the beginning, when this InventoryClickEvent error appears, everything is unconfigured and starts to give an error too, here is a log of when I enter again after the save error.
