I do know when Geminiagree and elmawa made their worlds that both had to redo all the elevator shafts as all the testers had problems with all the highrises. So to my knowledge the only way to fix the highrises is good old fashioned rebuilding of all the shafts in the world.
There is nothing you can do about the bounce. It is especially bad if a person has vertigo (I do) or epilepsy or prone to migranes with aura. It makes us instantly nauseous the second that bounces. It bounces when you try and redecorate or if while playing the camera slides a millisecond outside the apartment. It's like somebody hitting you with a cloud of the worst case of nausua possible. I cannot see how it is possible to make it stop that.
Anything over two floors has always bounced in the sims, but it was never as severe as it is with high rises.
It's a shame too as I love the vamps and the clubs, but can't play BP unless I remove every highrise in it. Sort of silly to have it a city then.
Between those two problems though has to be the cause Bridgeport does not hold up. I actually played an altered Bridgeport where all the holes were fixed on the map some time ago - it was before Pets came out I believe - I used Overwatch and the world still deteriorates and gets very unplayable even before you can raise up one generation of sims.( I am not sure if that was hers or not.) The only way I could play that map was to stay on housing side and only use the lower clubs. I can't see how they can fix it myself.
