Experiencing this bug archived here in latest build with all DLC packs, no mods/cc.
The default Wedding Venue in Tartosa IS available, but no customly made ones.
I did just check the lot, however, in case there were some new requirements for the venue - and it was acting as though the lot was a small business (even though it said Wedding Venue from the map). I reset it to Wedding Venue and it said about "deleting business areas" or something and now it shows up as expected.
Thing is, this lot existed long before Businesses & Hobbies did, and has worked before. So something changed the lot with the inclusion of that pack, I guess.
I put Build Mode and Live Mode because it's kinda both?
