The duplicate classes are one problem but not the primary one. You will easily run into problems in the simple situation where two plugins are bundling two different versions of statslite; only one will be loaded. Therefore if the API has slightly changed there will be always one plugin which breaks while the other one is working.
As a general rule, never shade anything in the default package if you can expect others to shade the same.
Afaik we had this problem with SpongeForge and Forge before, because both are shading configurateā¦!?
You should also compile your plugin with at least 4.0.3 or 4.1.0-SNAPSHOT because < 4.0.2 generate invalid plugin metadata files for optional dependencies, currently your plugin is not loading without Updatifier installed.
Edit: Your plugin actually doesnāt contain a mcmod.info, so the issue is somewhere inside SpongeVanilla. However, you should update your SpongeAPI dependency anyway so it can generate one for you. 
Iāll update this as well, thanks for letting me know!

It appears that you are targeting an outdated version of the Sponge API in your plugin. Try targeting version 4.1.0-SNAPHSOT.
thanks ! i test later (i need restart but i cant now ^^)

I have an issue where users are losing money slowly, for example a user will have 100$ and after a few hours of playing will have $60. An idea whatās causing it?
That is an odd issue, do you have any other plugins installed?
A fair amount: Essentials, Adminshop, Polis, PJW, Keys, PEX, Fox
They were saying it might be because of crashing or logging out, I got this from multiple users, but they did not know how they were losing the money.
I believe that this is caused by another plugin. I have run just EconomyLite on a Sponge server for an extended period of time and never lost any money. If it was caused by crashes or logging out, it would still be due to another plugin, as EconomyLite saves the data to permanent storage as soon as another plugin tells it to.
Alright thank you, iāll try and remove some and try to pinpoint which one it is.
