Solving this would require a complete rewrite of how the mod handles block updates. I haven't had any other complaints of people using SpongeForge. I'll keep this in the back of my mind when doing future updates, but won't change it as of now.

Thanks for using the mod and letting me know though! Never knew this could be an issue.

I have the same problem with SpongeForge :<
