I'm seeing a crash when starting the server with Building Bricks 1.3.0.

Client starts up fine, fyi.

I'm getting the same crash. I'm not certain but I think it's line 51 in the file ModBuildingBricksCompatVanilla.java. You may need a client/server proxy to only get that in on the client side.

Fixed in version 1.3.1, thanks for the report.
