Can't select venue for wedding events

@NessieAlways I've tried a number of things, including adding a wedding venue I made (a church built to work for wedding aspects) to the save. I went into the lot after it placed and changed the lot type to 'Wedding Venue', just to be sure, and it still did not show up as an option for wedding venues in the planner.

I also had a helper/friend test with your save in their game. They saw the same things you and I did - no venues show as options for weddings. However, they did point out that other types of event planning showed venue options, just not for weddings. They also pointed out that some lots that are normally locked had the lot type changed, and were wondering if there was a Mod you used for lot type edits or for other editing of the venues? For instance, he noticed that you had made the haunted house 'residential', and that the 'Tiny Home Residential' and 'Haunted House Residential' are now the only lot options there to change to when playing your save...

...Even though in an unmodded save that lot cannot be changed:

It's possible that if you used a Mod that changed some lot types that perhaps it broke the connection that's normally there to change/see the lot types for the wedding pack? For instance, my friend said on that haunted house they were not able to change it back to the original lot type. 

He also mentioned that perhaps you could experiment by testing in the save you created in which the venues appeared as normal ... you could test changing the "locked" lots with your Mod to see if the problem occurs again after doing that in that save?

Given the extent of the investment in detail you have in this save, perhaps it would be best to just have Sims elope in this save, since the wedding pack apparently cannot see lot types correctly as-is. You could save your experiences of a more involved wedding for a save you have not modified as much?
