This one is NPCtime's issue -- it has improperly updated for the tooltip changes in 10.0.2. The changes make it so that by default your tooltip handlers run on every tooltip, not just GameTooltip -- but only GameTooltip has the GetItem/GetUnit methods now.

It needs to either filter its handler to make sure it's only modifying GameTooltip (if tooltip ~= GameTooltip then return end), or it needs to replace its call to tooltip:GetUnit() with TooltipUtil.GetDisplayedItem(tooltip).
