Bukkit

What steps will reproduce the problem?
Setup a redstone circuit that relies on glass to block redstone current between a repeater and redstone wire

What is the expected output? What do you see instead?
The expected output is that the redstone power will not go from the redstone repeater through the glass and into the redstone wire on the other side as glass should not transmit redstone power. Instead, glass is transmitting redstone power through itself as if it is a solid block. This issue is resolved by removing the plugin but not by changing any of the options

What version of the plugin are you using?
Version 33, plugin version 17

Do you have an error log of what happened?
There is no error generated

Disable the blocks on glass feature. I will be coming out with redstone to be able to be placed anywhere next so that should clear it up.
