How patch this addon step by step.

1) Open your addons folder located on the game directory World of Warcraft\_retail_\Interface\AddOns

2) Open the folder BGDefender and RIGHT click on BGDefender.lua (If you don't see the extension ".lua", it's the one that weights 31KB) and select "Open with". Select More apps and select Notepad.

3) To locate the section, select this text without quotes "local bgInstanceMapIDs". Select the notepad window and press Ctrl+F. Paste that text there and mark Direction: Down, then button "Find Next".

4) Copy all these lines:

        [30] = "Alterac Valley",

        [489] = "Warsong Gulch",

        [529] = "Arathi Basin",

        [566] = "Eye of the Storm",

        [607] = "Strand of the Ancients",

        [628] = "Isle of Conquest",

        [726] = "Twin Peaks",

        -- [727] = "Silvershard Mines",

        [761] = "The Battle for Gilneas",

        [968] = "Eye of the Storm (Rated)",

        -- [998] = "Temple of Kotmogu",

        -- [1105] = "Deepwind Gorge",

    [1280] = "Southshore vs. Tarren Mill",

    [1681] = "Arathi Basin Winter",

    [1715] = "Battle for Blackrock Mountain",

        -- [1803] = "Seething Shore",

    [2106] = "Warsong Gulch",

    [2107]  "Arathi Basin",

    [2197] = "Korrak's Revenge",

5) Replace it with the text inside the section inside the brakets { and }.

6) Close the text file saving the changes. Win the next BG!

Is there anyway to increase the overall size of the addon?

You literally just have to open the file BGdefender.lua and replace the code with what they said.  No addon making skills required.

Just did it and it works for me.

In reply to Dethsesh:

 What does that even mean? IDK what any of that is!!! And it's "LITERALLY" the creator's job to fix their damn addon, not clueless users like me. If it's LITERALLY that easy why haven't they done it??

Fix yo' stuff!!

I'm going to go kill more Alliance now.

In reply to stormbornravenpaw:

 If my son ever left comments like these on the internet I would cry. 

This addon no longer works in any bg. It used to work just fine. I've reinstalled, reloaded, messed with the settings, etc. It's Dec 18,2020. Please fix as the ex-pac has been out long enough to fix this. Please don't tell people to go into the command or code or whatever the hell it is and type all sorts of = brackets, commas, etc. Because if I knew how to do those things, I'd be making addons. 

I need to kill some alliance now. This has me frustrated.

BGS that I've done today : WG, Ashran, Arathi, Isle, EOTS, Deepwind G., etc. It didn't work in ANY of them. 

Please fix. PLEASEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

Update this section in BGDefender.lua to improve things a bit.:

    local bgInstanceMapIDs = {
        [30] = "Alterac Valley",
        [489] = "Warsong Gulch",
        [529] = "Arathi Basin",
        [566] = "Eye of the Storm",
        [607] = "Strand of the Ancients",
        [628] = "Isle of Conquest",
        [726] = "Twin Peaks",
        -- [727] = "Silvershard Mines",
        [761] = "The Battle for Gilneas",
        [968] = "Eye of the Storm (Rated)",
        -- [998] = "Temple of Kotmogu",
        -- [1105] = "Deepwind Gorge",
	[1280] = "Southshore vs. Tarren Mill",
	[1681] = "Arathi Basin Winter",
	[1715] = "Battle for Blackrock Mountain",
        -- [1803] = "Seething Shore",
	[2106] = "Warsong Gulch",
	[2107]  "Arathi Basin",
	[2197] = "Korrak's Revenge",
    }

^^^more better

You can try this 

https://www.curseforge.com/wow/addons/bgcallouts

not as slick but caters for the new stuff

In reply to Forge_User_32150659:

 BGCallouts doesn't work at all.  tried it several times.

Any chance this mod can be updated to work with the new versions of the BG's as well, like the new Deepwind Gorge which is now a CTF.

what does the "p" and "m" stand for?

In reply to Forge_User_05133011:

m = movable

p = stay in postion.

maybe try to find string "function BGD_isInBG()" 

and modify two instance(or map?) ID

[2107] = "Arathi Basin",

[2106] = "Warsong Gulch",

thank author 

In reply to ZiyueFang:

 This worked perfectly. I simply added this to the LUA :

In the BGDefender.lua file, I added your idea after line 315

[2107] = "Arathi Basin",

[2106] = "Warsong Gulch",

Add those to the file and save, worked like a charm. Thanks for pointing this out!

Would REALLY love to see this addon get update. Its a godsend.

BG Defender is no longer working!  I'm either told I'm not in a bg or I'm not the leader????  Please fix this ASAP.

There is a new kind of BG called a Brawl; one of them is in Arathi (only it's winter, and misty), but even though it's the same map, BGD doesn't recognize it as a BG. I'd be grateful if you could add it. :-)
