Hi there! I originally did consider the option to throw funerals on Generic Lots (I think that’s what you mean by General lot?), but decided against it in the end. Events aren’t normally configured to happen on Generic lots, and while it can be done, it takes a few tuning changes and overrides, something I don’t really want to do for this event. I did it for the Prom Mod and it’s sort of a pain, hehe. There’s also the bug that happens when placing venues on Generic lots- and it was/is such a headache for the Prom Mod, so I don’t want to have that issue again, lol.
That being said, I highly recommend just throwing funerals at a lounge. Obviously, you can take a church lot (the lot I made is a lounge too) and turn it into a lounge. One way to skip the lounge requirements is by placing a basement with no access to it and placing all the required objects (things like barstools, tv, stereo, etc.) in it- that way they’re not cluttering up your church lot :) Most other Sims don’t seem to visit lounges so they won’t ruin your funeral, and the ones who do are usually seniors (that’s the way the lounges work in the game, haha), so that’s somewhat fitting for a funeral, anyway, LOL. Or you can throw them on residential, park, museum, or restaurant lots :)
Anyway, sorry for the long explanation, but I hope that helps :)
