Building a very detailed house, use moo & debug items also, & keeps randomly happening to a few windows, also happened in basement to door frame, big & small one, also I overlap my windows' frame a little, don't know if that detail matters. Other details; 2 story house with basement & pool is in foundation. Build is in newcrest on hillside highlands lot, & I use some platforms, 1 step higher & lower, on all floor levels of house, & the bug happened on all 3 floor levels, and only fixes when I remove & place door or window again, though I'm in middle of building on it for days, & not sure if it will only happen when I'm building, or if will when playing live too. Happens many times, diff windows too.
*Probably should note this other bug elsewhere too: not sure if it could be related, but ground can't level flat, not sure if it happened after making pool or platforms, but on left half side of house, foundation slants up wall a bit, I can't edit it to flat, can dig down into it though but only steeply..I'll have to pay attention next time I build, after certain steps, to find when something like that first happens or what causes it so I can undo in time, & report the cause.
Very busy so probably can't check on here anytime soon to add more info- just wanted to take a moment to "me too" in case it helps, with details that might help.
*also unrelated but: If I have time in future, maybe it could help if I also started a post that might give insight into game lag issue work around I found, for issue with lag going into build mode people had. It has something to do with dine out restaurant lot, or maybe island living installed, but mostly I think dine out restaurant lot started it.
All I know is, game was fine, not laggy, then added those two, seemed OK but background took while to render, probably because I had turned view distance off. Went to visit pre-made restaurant, so laggy, was terrible, got home to tiny 1 person house that was fine before, lag wouldn't stop especially worse in build mode. Got ea to remove those 2 games, & lag bug still there, repaired game, still there, cache cleared by the way still no help. Only thing that fixed it, seems when I went in options, turned view distance back on, put lighting on medium, reflections low, edge smoothing to low, played again, saved, went back in game, left view distance high, but put lighting low again, edge smoothing back to off, reflections off.
Some reason, the lag left my game just because I changed graphics around a bit. No idea why that was, & wonder if telling ea about this can figure out why people get severe build lag, & narrow it down to going into a restaurant setting it off. Or having island living, but even island living seemed fine before I went into a restaurant, except distance rendering slow.
Have a feeling dine out is the problem that introduces severe lag.
Sorry I don't have time to post that on its own post, didn't even mean to detail that far, have so much to do, I'll check if any response in future, may take long while.
