This problem has actually plagued me in the past before, but I could never figure out who the culprit is. I was walking along the platforms that lead to the store in Seyda Neen, and I noticed the one in the corner was missing.

Try indoril spear. I think there were some type of issue with it.

Yeah, indoril spear doesn't even work. None of the Indoril guards carry them, and I tried giving them the indoril spear through the construction set, but I couldn't drag it for some reason.

I'll try it.

Whoa! Disabling Indoril Spears fixed it! I didn't think I would get a solution for this problem, to tell you the truth.

Anyone know why Indoril Spears would cause this problem in the first place?

Dirty reference in the file. Do you know how to fix those?

edit: I don't like ending in a question like that: You can fix a dirty reference using the http://planetelderscrolls.gamespy.com/View.php?view=other.detail&id=52 or by flagging the reference to "ignore" it in the CS (someone correct me if this method doesn't actually work).

Sloppy modding

You can erase the reference with Enchanted Editor, or flag it as Ignored in the CS.

You guys mean like gmsts? I thought I used tes3cmd to fix it.

I guess tes3cmd missed indoril spear when I used it to clean all my mods. I just manually cleaned it with tes3cmd, and it removed a bunch of stuff from there, but the platform still goes missing. And I only checked the clean version of indoril spear.

GMSTs are different than dirty references. When the author of that mod made it, they moved, or in some way edited that platform (in this case it looks like they deleted it) - that change was included in the mod. To remove it, you have to manually go and delete (or ignore) that reference.

GMSTs are basically a dirty reference that is automatically included if you have TR and/or BM installed and try to make a mod which is only dependent on MW.

I'm so confused... so can tes3cmd remove dirty references then?


EDIT: Oh, I guess I didn't read the read me on the site for tes3cmd thoroughly. I only rid my mods of gmsts.

I'm not familiar enough with tes3cmd to know what it's capable of. There is no simple script to remove dirty references, that I know of. It has to be done manually, so you have to know what you're looking for.

If you have the CS open, go to open a file, select the indoril spear mod, click details: it'll pop up a list of all references included in the mod - I assume there shouldn't be too many for that mod.

Sort by ID (by clicking at the top). Now you're going to be looking for something named ex_de_dock_01 (or something similar I think - this is off the top of my head). Select that entry and hit Delete. The entry will now have an "I" next to it, and that reference will be ignored.

Hope this helps a bit - if you'd rather use Enchanted Editor, it's pretty easy in there too. I just prefer using the CS to keep the multiplicity of programs I have to use to a minimum.
