Using simple empty plugin-jars with a plugin.yml as shown in https://paste.gg/p/anonymous/891ec9c4140249e2ad6d9ff94122fa8f it would be expected for the load order to be FastAsyncWorldEdit -> GriefPrevention -> Pl3x however as seen in https://paste.gg/p/anonymous/77e7e8a9ab074308b678b07da9548307 the load order is in fact FastAsyncWorldEdit -> Pl3x -> GriefPrevention.

With FAWE providing WorldEdit, and GP soft-depending on WorldEdit, the load order does not work, however, with GP soft-depending on FAWE, or FAWE being called WorldEdit rather than providing it, the order is correct.
