I've used this mod for a very long time and never had this problem... When I try to use the Ascadian Rose Cottage travel scroll, nothing happens. I mean nothing at all, I can't even read it, even though a check in the CS shows it does have text and the script is properly attached to the object. I have that mod merged with a bunch of other house mods, but I had it merged in my last setup without ever having this problem. Anyone know what might be going on?

Here's my mod list. I'd post it according to load order, but I can't figure out how to make Wrye Mash do that.

A lot of things are merged, but mostly I kept it to merging several similar mods by the same person; the MQB addons, for instance. The merged house mods are:
Abu's Manor
Abu's Retreat
AK_IndarysGreathouse
Archmage's Tower by Antares
Ascadian Ship Home
Ascadian Rose Cottage
Balmora Council Club
Bloodskaal House
bm-house
Clean Princess Factors Estate
Clean TirnaOg
Clean_WH_Well House
Dagonview House
Firemoth Expanded
Japanese House
New Rethan Manor
Patriarch Living Quarters
Princess Pocket Homes
Princess Seyda Neen Shack
Rain's Hand Hall
Seaside Cottage
Solstheim Zelda Estate
Steinthor Hall
temple_apartment
Vivec, St.Delyn Living Quarters [TBBM]
Vodunius_Nuccius_House_V1.1
Xenterra Keep

Most of which I ran together in my last setup without this issue.

Any help would be greatly appreciated!

Hmmm, some possibilities: another mod adds something with the same ID as the scroll and its definition supersede that in "Ascadian Rose Cottage Travel Scroll", similarly another mod may have defined a script with the same name. I'd start off by using Wingrep or InfoRapid Search & Replace to search active plugins for the ID of that scroll, and then the script. Alternatively do a "single vs all" check using TESPCD, with this mod being the "single."

BTW, I'd recommend running your plugin list through mlox. Few things to look at.

Ran the list through Mlox and got nothing particularly useful, other than notice of a few redundent bugfix mods. I don't have Wingrep, so I'm checking the ID and scripts manually, but it's not looking like there's a double anywhere; the ID and script are pretty unique, although I'm not quite done verifying that. I did open the mod (since the problem mod is combined with the other house mods) and the script attached to the scroll looks right; meaning the script references the correct NPC and nothing seems messed up or replaced there.

Is that the only possibility, or is there anything else that could have gone wrong? It's a small problem, but a particularly annoying one...

Um. Apart from trying a http://www.mwmythicmods.com/argent/tech/bin_srch.html or re-creating your merged mod without Ascadian Rose Cottage I'm a bit stumped.
