Plex-FAWE/src/main/java/com/sk89q/worldedit/EditSession.java
sk89q 09f3364d9f Moved the block data check to LocalWorld, adding preliminary support for custom blocks. 
All unknown blocks are now assumed to carry data, and so this will also future proof WorldEdit (for the immediate future). However, be aware that full custom block support requires carrying TileEntity data (and perhaps other data) and that is not yet supported.
