WorldEdit's //setbiome stops working while JEID is installed.

[WildArticunoAppeared]

I'm trying to change the biome of a structure to one that would support the mobs that spawn in it using WorldEdit's //setbiome command.

However, //setbiome stops working completely while JEID is installed. It says it changed the biome sucessfully but no matter what I do (leaving and re-entering, using different biomes), nothing actually happens. Not one block has its biome changed.
