@JuliaChang93 I have a couple of thoughts that may or may not be relevant.
@crinricti will try this house and have you informed ^_^ For both cases i would like to share the information about these residential lots, i also downloaded them from the gallery and in case of some copyright issues i am giving directly the names: (lel)
"Sulani Dream Mansion" by KateEmerald (i was using it on 50x50 beach lot in Lani St. Taz, Sulani)
"Chateau Peak Renovation" by lilsimsie (i was using it on Chateau Peak lot in Del Sol Valley)
Update: Okay, that's a very sad moment for me because in this house (Bedlington Boathouse if i am not mistaken) everything looks fine... stairs making no trouble.
@SheriGRBefore trying the stuff you mentioned, i firstly want to ask if "localthumbnailcache.package" is as same as "localthumbcache.package", because i have a document named localthumbcache instead :/ sorry if it is weird to ask, i do not want to crash anything so better safe than sorry haha. By the way i guess "bulldoze terrain" would work to get rid of these grass tiles if there were some, right? After doing so, nothing has changed... :/
@PriestessAvenara, i added another main door connecting directly to the road without stairs and it worked. But unfortunately it ruins all context of the house, brainless guests only hanging around in my bedrooms lol (joking, actually not a very big thing to deal with, the real problem is it happens all the time :/ )
@JuliaChang93 Yeah, I suggested in the back because I figured if it was put in the front NPC friends would use it too. I have a door to my backyard and never have a problem with guests entering it. Although a few have visited and walked out it to see my garden, they always leave out the front by the street. I'm sure your dog will do ANYTHING to get to a place to use the bathroom, back yard included. Although to be honest when I had a dog in one of my games he always chose to use the front door over the back yard one. On the other hand I didn't have a porch or stairs. My logic is if kids will use ANY sink to clean their plates, even upstairs bathroom ones, the dog will travel to the backyard if that's the only door that it thinks it can use to go to the bathroom.
I don't know about you, but I'd be disturbed by people wandering into my bedroom instead of the main house. So yeah, I'd probably either want another more dog friendly house if the dog won't use the backyard door...or people started using the backyard door instead of my front yard one like I want them to. I admit there is a possibility of that since the game might assume you want your guests to go into your first floor. I'm pretty sure there is a choice to "Make this door my front door" (or something to that effect) when you right click a door and have more than one outside. So that might fix people using the wrong door if that happens. Meanwhile, I'm pretty sure your dog will choose ANY way out over your little porch. Haha. It is potty trained after all.
@JuliaChang93 Oh my goodness... I'm so embarrassed... yes, localthumbcache.package is the name of the file. Wow... sorry for the confusion. I will correct it in the other post so as to not confuse anyone else. I just tried bulldoze terrain and it did nothing to the tiles used (grass, cement, etc.) on The Old Salt House. You will need to use the sledgehammer on each grass, cement and other tile in the yard to delete any of them and get down to the real grass.
@SheriGR I have to admit. I find it really confusing that there would be a lot using grass tiles instead of just letting the grass show through. I've never used that lot before so I had absolutely no idea that could be a problem. Admittedly, things like this are the reason why I like visiting the bug forums. I learn new things. I admittedly wonder now if there are other lots that put tile everywhere, even grass tiles over grass.
Now here is a question. Say someone took the time to get rid of all the grass tiles and upload a lot without them. Would putting that uploaded lot down over a tiled lot get rid of them since the upload doesn't have them?
@PriestessAvenara Yes, placing a lot on that lot should overwrite all content, lot traits, flooring & terrain with the new ones.
