I dont understand why devs do this. The house looked fine. No one - I mean NO ONE gives a damn about the house/background used in a porn game. As long as the background looks O.K. (it does) then there is no need to fix what isnt broken. Instead, that time could be spent drawing sexy scenes.
What a waste...
Why do they do it? It's usual the main developer stalling for time or money (usually both) with only the rarest of exceptions. Burning good will or wasting time doesn't matter; the most optimistic of folks and the most paypiggiest of paypigs will always either forget that they're supporting devs until they get update emails or just fully trust the devs even when they get screwed over (aka, idiots.) The people who rightfully filter out due to the content drip-feed or blueballing leave and get replaced with more folks who will fall into either category again. Repeating the remodel/redesign phase ad nauseum whilst only giving fractions of new content compared to the initial 2-3 releases when they had little support.
Now, if the house update was more than just a light visual change, and added more locales for events/scenes, that's fine, but visual tweaks are straight up just to stall for cash, rather than to improve the product in forward-moving, positive ways.
