Yes, but we don't get to see how long this exactly takes place after she left the group.
Yeah let's. Before I end this I still want to make one more point why in this case I disagree with your viewpoint (just for sake of clarity to everyone who reads this):
The main reason I think that way, was simply because of the simple rule of determining the rules of the world where a story takes place in. Everything we saw in LoF exists also in our world: The buildings, the vehicles, the technology etc. There was nothing advanced in it so we don't expect anything advanced to exist. Since u4ia takes place soon after LoF, we don't expect technology in this game that is way more advanced than we already saw. However
if they began numbering the androids with #1, this means there were already more than 20 created before this game and we know the last two (unless there are already more created after Nyah) are/were extremely close to being human (otherwise he wouldn't be able to marry). You would expect at least some sort of less advanced androids to be visible in the background or in the newspapers. However it could be that it's in the news(papers) of LoF and I just didn't remember/read those because it had no impact in LoF.
This makes me want to play LoF again
