Hello, I've been getting this LUA for the past week or two:

45x Cell/RaidFrames/MainFrame.lua:283: attempt to call upvalue 'GetGroupMemberCountsForDisplay' (a nil value)
[string "@Cell/RaidFrames/MainFrame.lua"]:283: in function <Cell/RaidFrames/MainFrame.lua:282>
[string "@Cell/RaidFrames/MainFrame.lua"]:330: in function <Cell/RaidFrames/MainFrame.lua:322>
[string "=[C]"]: ?

It happens when hovering my mouse over a raid frame unit.
