I apologize for making a new topic when I have one still on the main page, but you can't double-post and editing my post wouldn't get it any attention since it's not going to make it "new" or anything... But I've run into an issue I'm slightly confused by. Nothing major, so it's easy to answer. Just, having returned to Halo only days ago and trying to remember everything as I go along, this one makes no sense to me.

So, I wanted to test out a couple quick tag modifications to see what I remembered, and extracted the scenario for Hang 'em High since it's one of the best maps in my opinion to test out weapon tag modifications, only for Sapien to close instantly when I loaded the scenario. I checked debug.txt, which I'm proud of myself for remembering after 2 years of not messing with HEK, and here's what it said:

Now... ... why do I need a shader for an Elite to load Hang 'em High again? Because it seems like Sapien put on it's trollface.jpg suddenly. I never remembered needing that, and I thought HEK included all default tags. Where in the world do I get that tag if I don't already have it (which I don't, obviously)?

Also, ignore the silly topic subject. I have my moments.

11.25.10 04:48:06 characters\elite\shaders\shield plasma.shader_transparent_plasma

That's the only tag you need to get this working again. So, I would recommend opening any Bungie map with HEK+, finding this tag, and extracting it.
Hopefully it'll work.

Couldn't find it, but I think I found the problem. I had compressed the tags folder into a .rar file just in case, so I deleted all my tags and returned the defaults to their original condition, and tried to load Hang 'em High, and it worked just fine. Apparently one of the tags I had downloaded was corrupt somehow. I just don't know which one, or if it was significant to me or not.
