Surprise attacks when moving from maps would be kinda possible, but what were you thinking on more specifically with this idea? Maybe could you provide a scenario or example?
Night events might be a bit more complicated, but depending on the type of events, something like moving to another map and getting lost as a random event could definitely be possible, I don’t know if it would be annoying however.
Maybe a consequence of high lewdness, or high lust, if you don’t treat it you have a bigger chance of getting lost, being attacked and only returning at night?
