Hi! I've tried to build HSP by myself (it's a little bit complicated task) because I need WG 6 compatibility and there is no public build with appropriate commit (ec520b1 or other, I don't know if it is working already). I'm building latest commit (6388ff4).
HSP loading and making NPE at WorldEditRegion.java:124 (worldGuardRegion == null).
Can you make stable build with WG 6 support please?

Sorry, I'm a blind.
Found Jenkins link on DBO and there is latest build. It seems to be working good so I think mentioned problem was caused by my wrong build environment.
Could you add Jenkins link into readme file? :)

Glad you figured it out. I've added some notes regarding building the project to the README for those who would like to build it themselves.
