6.1 Caster blocks
Just so everyone knows we are looking into the caster block problems.
It doesn't appear to be a situation where every caster block is bad but there are some that seem to have some kind of injection flaw. The situation is being looked at.
One thing that I have asked a couple people to try that they have reported positive results is boiling the blocks in water for 5 minutes. Please allow the water to cool to room temperature on it's own, do not dunk them in cold water after boiling them. Sorry for the problems.
