I contacted Qazaaq this morning, and he replied quite quickly. When he has some time free, we're going to look at the LtPD ESPs and have a small update released for the mod. This update will undelete and disable all deleted records, and will remove all identical to master records too. Some records are intentionally identical to master for compatibility with Glenvar Castle and UL Imperial Isle, Qazaaq is hopefully going to tell me which records these are (if he can remember) to ensure they remain in the mod if still needed.
You sure LtPD needs ITM records for compatibility with UL:II? I'm running both and cleaned them both quite thoroughly and have yet to notice anything out of place simply by sticking to the usual load order of having LtPD first, then the UL after.
I would also assume any shenanigans with ITM records would be a moot point if LtPD loads after Glenvar but I don't run Glenvar and haven't checked that one recently.
Also, you may want to remind Qazaaq about the _far.nifs and see if he's still planning to run those through the PyFFI spell to clean the files. I told him about those awhile back but he may have forgotten.
