When both Krowi's and ElvUI are loaded (in Cata Classic), this error pops up in Krowi_AchievementFilter/Plugins/ElvUI.lua as shown below. It looks like the code is trying to handle the special case of ElvUI being loaded, but something goes wrong? I do not get a LUA error when one is loaded but not the other, however that is not the desired result. This error is being logged by BugSack on character load-in. I can disable ElvUI's skinning of the achievement window as a temporary fix, and the error does not occur.

Thanks!
