Thank you for the mod. It adds a nice variety to the game and can be easily customized to your needs.
I have a question about the "trackExpGain" parameter in "xleveling" config. I have deployed a dedicated server where we play with friends, but there is no experience gain displayed in the chat. Although the setting is set to "true". I remember that I had a similar problem in the singleplayer, but the problem resolved itself there, at some point after several hours of playing - gaining experience began to be displayed in the chat. This does not happen on a dedicated server. Maybe I'm missing some settings in the server itself?
Edit: somehow, the problem resolved itself again, after a few days of playing on the server, a chat channel with notifications about the experience appeared by itself.
