Should those not having the bug also post their list, so as to make eliminating innocent addons faster?

@DZHEX, Actually, that be a good idea, as long as they have the addon installed, then sure they can post their list.

NO BUG
A way too long paste here: http://pastebin.com/6Xz9f5C7 - 129 addons total
Will try to post just the titles right here once I get some lua skills straight

Update: uhh, now that I saw the list of titles, I realized quite a few aren't very desctiptive... And that I should probably do a cleanup.
I used this command:
one can replace "title" with "wsid" or "file", whatever Kidnation needs.

If you use i as the iterator, the comment thinks it's supposed to be italic and screws up formatting

@Archangel I deleted your comment because this thread is specifically for the SPAWN_MENU nil error

Bug present:
Since I am having the problem described, here is my addon list. Hopefully you may find something in here.

https://pastebin.com/y29pwVrW

The console output when attempting to open the menu (for my due diligence) is:

[Zombie/NPC Invasion (Fixed)] lua/autorun/client/tool.lua:139: attempt to index global 'SPAWN_MENU' (a nil value)
1. DoClick - lua/autorun/client/tool.lua:139
2. unknown - lua/vgui/dlabel.lua:232

Experiments have shown:
On my machine it's been original ZINV.
How do I know this?
1. Experience error
2. Read desc of both addons
3. Unsub JASON's ZINV
4. Restart gaem
5. ...
6. Profit
Seems likely either.

Hello there! I think this sounds like addon conflicts which causes some of your files to not even load. I took a look at your addon and saw that you're using generic names like init.lua, gui.lua in lua/autorun. That's bound for trouble.

Autorun files must have a unique name since all addons put their files in that folder. Source engine doesn't separate them, the first loaded file wins, all others are ignored. Since your .gma file starts with "z" it'll probably lose. You won't notice this during development, since folder addons are loaded before .gma addons and therefore always win.

I recommend you rename you're files like that:
yourname_zinv_init.lua
yourname_zinv_shared.lua
etc.
Don't forget to change all references in all lua files.

Can't guarantee that this fixes all possible conflicts. Anyways, thanks for maintaining this great addon. I hope this helps a bit.

Yes! This sounds like the thing I've been missing. I'll have a see if this fixes the problem

@LibertyForce, I've renamed the files, and gave them the correct references, so we'll see what happens.

The coliding mod is Complete ULX Pack with CC

for some reason lua_run doesn't work, is it certain it's an addon conflict? It came out of nowhere without me adding new addons

Edit: Add addon with uncompitable list
http://steamoss.com/sharedfiles/filedetails/?id=862644776

I may found out it the cause of this. It seems that this kinda messes up your config after you add a lot of NPCs and sometimes it adds the default npc_zombie, npc_fastzombie and npc_headcrab_fast incorrectly, thus breaking your table. When it does that, the Spawn Editor still works and you can add new NPCs to the table, but it won't save. After you reload your map, you will see that after trying to open your Spawn Editor, it will create this error as Tamer mentioned:

2. unknown - lua/vgui/dlabel.lua:232

I managed to fix this by going in to the data folder (steamapps/common/Garry's Mod/garrysmod/data/zinv/), removing the incorrectly added default NPCs from the table. They are usually located at the top of your profile file, you might have to look for the broken brackets and stuff. Needs more testing though, as it is kinda hard to pinpoint when that happens.

EDIT: Right now I added 3 heroes to my existing large spawn table. I reloaded my map and right before it loads, I get greeted by this error: http://prntscr.com/gl8qgh
My heroes that I added didn't save for some reason: http://prntscr.com/gl8qrj
Also you can see one of the errors in the table here: http://prntscr.com/gl8pff
This is located right at the bottom. It seems that you can't get over some kind of character limit. I have no idea. It just doesn't want to save properly anymore after you add many types of NPCs.
Here's a normal table with 2 heroes and 2 NPCs: http://prntscr.com/gl8sll
Of course it works fine, but It's kinda boring to fight with only 4 types of enemies all over again.
I hope this gets fixed.

I tried this, nothing showed up. By that i mean it deleted everything in the console.

Im not exactly sure if this tread is talking about the problem ive been experiencing but it sounds like it.

The problem Im having is that the entire zinv menu is gone, like if i go to settings zinv wont be there. And that so happens to be where the Spawn Editor is as well so I cant edit anything thats spawning in my game. If there is a command that opens this menu please tell me or at least help me find a way to fix this
