Hi Jerry99, sorry to hear that you are experiencing this issue too. It seems to be very widespread here on the ps4, and Im hoping the next patch will sort it out for us.
Im not sure if this falls into the category of operational overhead which you just described (Im not very knowledgable tech wise), but I do know that they somehow changed the way the game renders on consoles in order to make Mounts possible on them. If anyone better versed on this sort of thing feels they can better explain it, then by all means jump in. 
Yes I have found this also. I have done no additional building at my main base since the Mounts update. I have had relatively few crashes in the past, only a handful of them. However, I am now having them almost every time I play. However, as myself and Tselem have said, it feels like the Admin Panel somehow worsens this, or ‘helps them along’.
Jerry99 I have also compiled a list of other issues which have emerged since the recent patch. I encourage you to have a look in the below thread, and let us know if you are experiencing any others on its OP list.
