When attempting to put a Fluid Supplier pipe next to a shield controller from StargateTech2 i get a java.lang.ArrayIndexOutOfBoundsException: 6

I reported this to StargateTech2's developer first and he said that the issue was on your end.
If you need any more information, tell me

This is not an issue on our end. We ask the conected block for the unsided tank information (ForgeDirection.UNKNOWN). Stargatetech2 apears to be missing either a check for unknwon or needs to extend a some arrays.

What happens if connection on 'unkown' is refused?
Do you go for the side you're actually connected to?
