I am not sure about this issue where to post it, because it involves 3 mods. So i guess I will start in here.

I am a developer of InfiTech 2 modpack where I have Railcraft and other involved mods. One of my testers have come accross the problem with said Steam Turbine. When he attaches Void Pipe to the bottom of the Turbine and put a block next to the pipe, the game crashes with Tesselator/render error/crash.

Here is the crashlog: http://pastebin.com/3ymMhEt3

Railcraft: 9.3.3.0
BC: 6.0.18
Forge: 10.13.1.1223

And here is also the link to the raised issue on the modpack Issue tracker for possible more info (including a screenshot): https://github.com/JasonMcRay/InfiTech-1.7/issues/82

Can we confirm if the crash occurs only when next to the steam turbine? Or any tile entity?

Update: 31/10/14 - issue seems to be totally related to buildcraft and not RC or chisel.
Testing parameters: Fresh World, Void pipe, trying to place vanilla stone blocks around the pipe, result was the same tesselator error.

I apologize for any inconvenience caused.

Thanks for updating us!
