We have noticed the 0.5.1 update of Create, which is sure to break compatibility for the vast majority of non-MCR addon.

For CCK, I, @MarbleGateKeeper , will first try to finish fixing all known bugs. I say this because the CCK lead program @RaymondBlaze will be busy until the end of June. I will start migrating the mod to Create 0.5.1 regardless of whether all bugfixes are completed or not.

The update is expected in early June, please wait patiently.
