Describe the bug
Lua error every time I login and using /reload. While I don't really use census info in guild window, I would prefer to get rid off this error.

To Reproduce

1. Install CensusPlusWotlk-v0.9.16-wrath.zip version
2. Login on character
3. Now you see Lua Error.

Expected behavior
No error.

World of Warcraft Information:

• WoW Version: 3.4.0
• Addon Version: CensusPlusWotlk-v0.9.16-wrath.zip
• Other Addons used: many of them, tried to turn off guild-related, no luck. Seems like this error related to Census itself

Additional context
I will happily help test fixes if you want

Fixed in current version
