No matching signatures to "ApplyTeamTextures(string, int, int)"

Hi guys, I'm trying to update Factions for the new KAG update, but I've gotten stuck.
The issue is in line 105 in the file RunnerTextures.as, with getRunnerTeamTexture, but I've no idea why! The mod runs perfectly fine (albeit the migrant having no head), but there's nothing in the mod that changes RunnerTextures.as, or anything that RunnerTextures.as has included. I also checked through runnerhead.as, and it doesn't use the ApplyTeamTextures function, and I don't think that it uses any function that calls that function.
The full error:

If you could provide any insight as to why the mod isn't working, I'd like to know...

 

Double includes are not handled correctly in mods. For example, a script A.as is not loaded if B.as includes C.as and C.as includes A.as. In your case it's necessary to include PalletteSwap.as in RunnerHead.as (before RunnerTextures.as). Please confirm if this works.

 

I believe it did work. Heads are invisible, but I think I know what the problem is there. Thank's for your help @Fuzzle !
