There is at least one hidden tomb door which functions as you’ve described, and is intended to be transparent in build/buy mode. I’m not sure what tomb-building mechanics you’re using—if you’ve already begun linking triggers to other objects, if you’ve placed hidden room markers, what the lot is zoned as, etc.—which may be affecting things? Perhaps someone more experienced in tomb-building would know if this is normal behavior. Does the door/window transparency problem occur when building anything else, or only with this particular lot?
Another thing you might try is deleting your cache files.

The bulldozed house being visible in map view instead of your new house is a relatively common visual glitch. It can be solved by going into build or buy mode and altering the lot in some way. (You can build and delete a single section of new wall or fence, place/replace an object, change/change back the roof color, etc.) Making a change like this will force the game to refresh the image. After you leave build/buy, your house should appear correctly in map view. I have this issue from time to time, and the solution has always worked for me.
Do you use CC/mods? My first thought with the discolored mood meter is that it sounds like something that might be caused by mod incompatibility. I’d try a factory reset and test a new save to see if the error is resolved, and then go from there. https://sims3.crinrict.com/en/2011/06/tutorial-resetting-the-game-to-factory-settings-without-reinstalling.html
