Current session in LDL only says from start of the game client to end of the game client.
Current UI reload only shows what was added since you did a reloadui -> Should be enough for testing imo.

"Avoiding cycle on table" is a debug output of the d() function in eso source code.
function d(...)
for i = 1, select("#", ...) do
local value = select(i, ...)
if(type(value) == "table")
then
EmitTable(value)
else
EmitMessage(tostring (value))
end
end
end

Within EmitTable then:
if(tableHistory[v])
then
EmitMessage(indent.."Avoiding cycle on table...")

It shows you that the d() output somehow triggered a table and no String to show in chat. > Your line 12 in file QuantumsGlobalAchievements.lua
So one of your parameters in your d calls seems to be a table, or at least gets recognized as a table.
