Please note that the mod loads without errors on the client, seems like it might be a client side only function that is being called server side?

Thanks for all the hard work Rikmuld!
Loving the mod so far

Error_998

Fixed the server error (see the repo of RikMuld's core for the fix) and tent render error. I will release a new version including these fixes soon.

I just updated :)

Hi Rik,

Any chance we will see this new version soon? As CampingMod has worldgen, if it is removed from the server it causes horrible chunk tearing on new chunks due to the seed change.

In particular, this is a big issue on modpacks with prebuilt maps like Tolkiencraft where worldgen is broken just outside the spawn region. (see:http://i.imgur.com/edOpnVf.jpg)

If it makes it any easier, I'm happy to offer a Jenkins server for you to quickly compile on in the future.

Thank you!
