I am unable to place the Redstone Port in the top of the reactor and have it face up. All of the other controls and ports, that I have tried, controller, power tap and access port, place and work fine in the top of the reactor.

2 things that erogenousbeef will need to help with this is, 1) what version of the mod are you using, and 2) can you supply a screenshot of the issue?

...0.4.0rc9.

...as requested.

Thanks. This is an oversight when changing the texture rendering code, but may have implications for the redstone connectivity code as well.

I'll look into it for 0.5.

any news about this bug, trying to fit my reactor in compact machine and Material Energy ^4 has no computer craft nor rednet available :(

This is tagged for 0.5, so it's going to be a while.
