MapInitializeEvent cannot be triggered asynchronously from inside synchronized code. #109
Description
Describe the bug
I have created a plugin which creates an image and places it on ItemFrame, the code works fine for all other forks or paperspigot or spigot itself but gives an error in WindSpigot.
