Jester menu isn't centered in main GUI viewport

[bones1014]

I'm exporting some displays to external monitors. I don't know when it started but the Jester menu isn't centered in the main gui viewport. I found an error in the JesterAI_Page.lua

Line 10 should say find_viewport("GUI_MAIN_VIEWPORT")

nullI included a screenshot of the way it's currently displayed and a screenshot of the lua with the error.
