saveConfig() not saving the config!

I added a few player names to the config(from ingame) and i checked if they actually saved, they did i could see them. but when i reloaded the config reset itself and the names are gone.
What i did look like:
Accounts:
List:
- Sup3rNinj4
- fafela
- candyshpownr

What it looked like after the reload:
Accounts:
List: []


Why cant it save properly!?
(Ive looked everywhere and cant find a solution that helps ._. )

 

Can you please post some of your code?

Post your code, post any stack traces.

You didn't look hard enough.

@MrAw3omeZz And the stack traces?

 

@MrAw3omeZz
Activate saveConfig after you added the player, and that will be better. Also, array lists resets every time it has been loaded!
