31 - Solution to 623 Error

Posting these here and on the Curse project page, not sure which one you check.

Determined the solution to the 623 error, I believe.  The problem is that ScanGuild() is called regardless of the delay you set, and that line attempts to concatenate a nil value (self:guild).  I don't know how to avoid the actual inability for the function GetGuildInfo to get the player's guild, but this solves the issue, by leaving the function early when it has bad data.  This is the diff file, with the 4 new lines (one of which is a debug line, without which this could be a single line).

    Patch 2.4.2 seems to have some oddly included libraries. The TOC is interface version 40300. And the .tga is missing.

    Back on topic. The way this current patch works, is that if self.guild isn't ready yet, then the addon sets self.scanning to true and is thus never able to scan the guild for the rest of that session.

    If instead, you set self.scanning back to false, then this function will be called again in about 15 seconds by the underlying scanning of Lib-GuildCheck. Eventually self.guild should be true and everything should soldier on.

    Whoops, might have loaded the wrong one by mistake. Just noticed i had 2 folders marked v 2.41 and 2.4.1.

    So close, and yet so far... looks like the changes in 2.4.1 didn't actually change guildcheck.lua, at least not in the ZIP file here at curseforge or on

    Sorry :(

    Sorry to tell you Jaxomuk, but the new 2.4.0 version does not fix the problem with the change from 10 to 20 seconds delay (I wasn't particularly surprised, since I had experimented with the same thing myself during the testing I did here).

    (FWIW, I had it fail on my 19th login to the game, and was able to reproduce it several times in a row afterwards.)

    I think if you want to fix this permanently, you'll need to implement either my suggestion above with or without roncli's addition below.

    I also added the following before the return with no ill effects:

    self:ScheduleTimer("ShowChanges", tonumber(self:GetDelay())) self.scanning = false

    This lets it retry later.

    Thanks Zelgar will put it into next update and Thank you, ive been chasing it for over a year and tried many possible fixes, non of which worked.

    Some background: I've had this error fairly consistently for the past year+.  I knew you had been working on a solution, and clearing a swatter error periodically on login did not bother me much.  It seems to happen to me about 10-15% of the time I login on a character, with no rhyme or reason to when it occurs.  About 2 months ago I got serious about tracking down how to fix this one, since it was just at the level of annoying.  I tried a lot of solutions, many of them trying to overcome the system not getting the guild information, most of them with poor results, and always tough to track down because of the inconsistencies with the error occurring.  After watching the debugging information several times, I realized where things were failing and the idea above came into being.  I have tested it *extensively*, and there is no harm; the next time ScanGuild() is called periodically (~15-20 seconds max), it handles the guild changes correctly.

    FWIW, this *could* be constructed as a:

    if self.guild then
     ... rest of function...

    But readability is fairly compromised, so I went with this solution to be quicker and easier to read, plus it allows me to add a Debugging line.
