I'm trying to zero in what's causing it, but putting here for Author to see/look as well

May have already found the fix, but in case there's more

I'm not getting the 2nd error, what did you do to have it pop?

Log in :(

Oh wait, I might know why, try Beta version, then the QuestID changes, author did code changes for Special Assignment triggers https://www.curseforge.com/wow/addons/wqachievements/files/5762643 (or download the zip from my pull)

Do you still neet to do the questID fix?

also getting this issue

2x bad argument #1 to '?' (Usage: local info = C_QuestLog.GetQuestTagInfo(questID))
[string "=[C]"]: ?

Locals:
(*temporary) = "bad argument #1 to '?' (Usage: local info = C_QuestLog.GetQuestTagInfo(questID))"

I did a replace all of questId to questID in the WQAchievements.lua file based on the fix posted above and now I get

I'm not getting the 2nd error, what did you do to have it pop?

Oh wait, I might know why, try Beta version, then the QuestID changes, author did code changes for Special Assignment triggers
