I have been working on an addon for a long time now, it's basically finished, the only problem I seem to be having comes in at handling leaving and joining guilds.
I obviously looked at other addons on how they do it etc but it looks like this problem is specific to my addon.

I'm saving guild data stuffs kind of like this:

savedVariables[gID].cats = "all of them"

Now, when I leave a guild apparently it sets the gIDs to something like 11-15 instead of 1-5 like it's supposed to. (this happens even before handling anything with EVENT_GUILD_SELF_LEFT_GUILD or whatever)
GuildIDs are taken like this:

	local numGuilds = GetNumGuilds()

	for i=1,numGuilds do
		local gID = GetGuildId(i)
		...
	end

Now my question is, (I don't see anything wrong here) am I missing something or am I required to use the guild leave events to make it work properly?
