When opening a world with the garden-stuff mod installed I get a crash. It seems to be a problem with an entity rendering. I have not installed any mod or coremod except garden stuff and chameleon.

Here is the crash-report:

I am not a coder or programmer of any kind, therefore I am not able to read the crash log myself to figure out the problem.
