I'm having an odd issue where my client install is running fine, but mirroring my mods over to the server is leading to a crash. Here is a pastebin of the crash - I'm using the most recent dev builds of Forestry, Railcraft and Applied Energistics.

Seems to be an issue with AE in the getRenderType() function @AlgorithmX2

@Pyro93735 are you sure your using rv12.b?

It was calling my getRenderType before i constructed it, I changed it for rv12.b.

ahh, that did fix it actually - not sure how I didn't notice that! thanks for looking into it
