Hello, so on my Survival Games server at random times an inventory bug appears. (Description) When moving items or equipping armor, it moves client side but it's really still in the same position. (Watch the fishing rod, after I move it to a different slot then re-click on the chest it goes back to the original slot) https://gyazo.com/47a5dd6352bbb02f2c250f1b659cd41b (Info) - Using Spigot 1.8.8, tried using paperspigot same results. - We support 1.7 clients as well, bug happens on both. - Our map system for SG copies a map from a folder with all of our sg maps, and duplicates it to our server world directory.
