Making test structures, I mistakenly glassed my turbine with reactor glass at one end. It still completed and operated.

I'm not able to reproduce this with 0.3.3A. If you're able to reproduce it, please post detailed reproduction steps and/or screenshots demonstrating the construction of the faulty turbine.

Made in creative mode, you can clearly see reactor glass at the coil end of the turbine, yet it is still fully formed and operational. The reactor glass must be placed before the last turbine block, further more, if the reactor glass is subsequently removed, the turbine will continue to function

Fixed in BeefCore: erogenousbeef-zz/BeefCore@d951a92

Will be out in 0.3.4A. Thanks for the report!
