Yes that does fix the Problem with line 6342, but then another one pops up that was not reported before.

StanoRiga · Answer 2 · 2020-02-16T19:40:40.000Z

I tried to fix the function "LearnNPCLocation" by adding
npcId = npcId or ''
in line 7535, but that led to other errors in "_AddNPCLocation" (as the empty ID is given to that function) and if I'm setting npcID there to 0 I have multiple errors in other lines (and as I am not sure what Im actually doing, I have undone my changes :) )

Btw: thank you for your quick reply

smaitch · Answer 3 · 2020-02-16T20:40:13.000Z

For the line I asked you to add earlier, can you replace it with:

print("*** learning for", mapId)

Basically I would like to see what the last mapId is before the crash because I do not know where it is coming from. I know it should not be nil, but it seems to be something unexpected.

smaitch · Answer 4 · 2020-02-16T18:35:12.000Z

Can you try to add the following line so it becomes line 3641 in the Grail.lua file in the addon:

			self._worldQuestSelfNPCs[mapId] = self._worldQuestSelfNPCs[mapId] or {}

It would be the line right before:

			local coordinates = strformat("%.2f,%.2f", x * 100 , y * 100)

Then can you try to see if that fixes the problem. As you can guess I have not been able to recreate the problem at my end.

DiscordGregory · Answer 5 · 2020-02-19T12:15:14.000Z

I have the same issue, I added the line you mentioned earlier and it says ***learning for 896

StanoRiga · Answer 6 · 2020-02-19T17:13:03.000Z

In my case its the following print out

*** learning for 62
*** learning for 62
*** learning for 62
*** learning for 62
*** learning for 62
*** learning for 62
*** learning for 627
*** learning for 630
*** learning for 627
*** learning for 630
*** learning for 646

smaitch · Answer 7 · 2020-02-27T04:57:49.000Z

Can you try to use the latest Grail on GitHub to see if the problem still occurs for you?

smaitch · Answer 8 · 2020-02-29T21:59:46.000Z

Thanks...that is some progress. I have updated Grail to hopefully handle this as well. It seems your Grail.lua saved variables may be in a weird state. Can you upload that so I can test with it? I ask because I have not been able to reproduce the issues you are seeing on any of my characters.

Sure :). Thank you for your support.

StanoRiga · Answer 11 · 2020-03-01T06:28:54.000Z

Just saw the update to 1.08.
This is the Grail.lua after the update. (just in case there are differences between them)

smaitch · Answer 12 · 2020-03-01T14:28:58.000Z

I did not mean the Grail.lua from the addons, but I meant the one found in

WoW/_retail_/WTF/Account/account name/SavedVariables/Grail.lua

where your WoW directory depends on where you have WoW installed, and the account name is the one that you use for logging into WoW on the character that has a problem. This Grail.lua is the saved variables for the addon that records the new quests and NPCs that it finds.

StanoRiga · Answer 13 · 2020-03-03T08:07:13.000Z

Ah, sorry. My mistake. Now the right one. (I edited the char names as Im not able to send you this via PM
Grail.zip
)

smaitch · Answer 14 · 2020-03-22T21:21:51.000Z

Thanks. The latest Grail on GitHub should fix this issue.
