What it needs, what it clashes with

Requirements

The Sims 4	Base game is enough. No expansion is required.
WickedWhims	Required. The mod does not include any adult animation of its own — it hands the scene over to WickedWhims.
Animations	At least one animation pack installed in WickedWhims. Without any, the scene has nothing to play.
Script mods enabled	Options → Game Options → Other → Enable Custom Content and Mods and Script Mods Allowed. Both.

There is no other script requirement. If you are carrying BQ_S4CL_Compat from an older version, delete it — it is not used any more and it causes errors.

What each expansion adds

Nothing here is required, but if you own them, more of the mod is in play:

• Get Famous — reputation exists in your save, so the mod actively shields the predator’s from the attacks.
• Se alquila / For Rent — rental lots are recognised as homes, so visits happen there too.
• City Living, Cottage Living, any pack with venues — more public venue types for public spawn.

Known conflicts

Nisa’s Wicked Perversions. Resolved. The two mods used to fight over the same sims; the mod now bails out early when a Wicked Perversions scene owns the sim. If you see the two interleaving, report it.

Other mods that inject into the vanilla fight interaction. The mod uses its own copy of the fight so that other mods’ extra requirements do not block an attack. If fights never start for you and you run a lot of gameplay overhauls, that copy is the part to mention in a report.

Mods that change relationships after sex. The mod deliberately freezes friendship and romance around an attack. Another mod that awards relationship for the same scene may undo that freeze.

If you play in another language

The mod detects the game’s language on its own. What is not translated falls back to English, never to nothing — see Translating the mod.

When you report a problem

The single most useful thing is the log. It is here:

Documents/Electronic Arts/The Sims 4/Mods/BQ_NightVisitor/visitante_mod.log

If your game is in another language that middle folder is named in that language — Spanish installs write to Los Sims 4, for instance.

Say what you were doing, paste the last part of that file, and list your other script mods. That is usually enough to find it without asking you anything else.
