The readme (as well as a note on the BOSS Master List) suggest Temple District Repaired isn't compatible with Better Cities. I asked about this on the Better Cities thread, and Vorians replied and indicated that they are actually compatible...
Temple District Repaired is fully compatible with Better Cities, as it doesn't add or remove anything at all, it simply toggles off the vanilla damaged pavement and toggles on the vanilla undamaged pavement using scripts - and BC doesn't touch either pavement. Load before all BC IC ESPs.
I did some testing and didn't notice any issues with Better Cities in-game, nor are there conflicts indicated via a TES4EDIT conflict report. Assuming you agree, should the note be removed from the readme and the BOSS master list?
