Should I clean Tamriel travellers from ITM? People say that Corepc was used to make his own plugin via tes edit and so you shouldn't clean them. So I'm kinda curious.

The same can be said for fcom plugins. Should I clean them from ITM? Why not?

If CorePC stated that the mod shouldn't be cleaned then do not clean it and know that FCOM is already cleaned since it need *dirty* records in order to work properly, which is exactly the same for Melian's Teleportation mod for Morrowind.

These mods need *dirty* edit(s) and therefore doesn't need further cleaning.

No reference inside the readme about cleaning it or not.

Truth is that the mod is listed amongst the 'already clean', inside this guide: http://cs.elderscrolls.com/index.php/TES4Edit_Cleaning_Guide

There are people claiming the mod causes CTD if it isn't cleaned, like firefly, in the mod's page: http://www.nexusmods.com/oblivion/mods/4387/?
