I guess it was a temporary glitch or a subsequent update might have fixed it. I know Wikia doesn't use the same code-editor as Wikimedia, but this was a bug filed :

There is probably some upper limit to how much highlighting the Ace editor can handle, so that should probably be noted somewhere. In my case it was a simple data luamodule that was automatically updated by a bot everyday for roughly 3 months.

"(Mind you: if a template is >80kb, that's a pretty crazy template.)"

But that's nothing, my favorite template when criticizing wikitext craziness and shamelessing pushing for lua is the monstrous masterpiece we've nicknamed it the DeathStar:

I should probably download it and save it somewhere, master pieces should be preserved :).
