What steps will reproduce the problem?

During the phase transition on Heroic Putricide (25-man), when we get the ooze and gas variable, RW2 throws an error when the phase ends.

What is the expected output? What do you see instead?

The addon still functions properly, I just get a lua error in swatter.

What version of the product are you using?

The latest 1.27 beta-final.

Do you have an error log of what happened?

Please provide any additional information below.

It's possible that this error has something to do with incompatibilitiy with the Acheron addon. I will have to try next week without Acheron to see if it persists.
