Hi ! I don't know if I choose the right topic and i'm sorry if i does it wrong.
So with a friend, we create a modded server, and I search for plugin to create an economy, so I change the version of my server, i choose SpongeForge, the server start well but when we try to collect an item on the ground or drop an item we crashed, the server stay online. I search on internet if the problem is a incompatiblity with a mod but i found nothing. https://pastebin.com/ZSvQgXy2 this is the mod list. And also there is no crash reports in the folders.
(sorry for my bad english it's not my first language)
