Last minute bugs

So I was away for a bit but am back now and am doing the last bits of wrapping up before launch. In the past two weeks, though, two issues came up. As part of my contracting I discovered that the iPhone X doesn't exactly have the same screen dimensions. Clearly I haven't even been testing in that sim. Fix was fairly straightforward. I am a little curious if it will also resolve an issue seen in Walking Tourist with the iPhone 6 Plus. There is no reason it should, but I am curious...
The other was a fix for a rare but persistent crash apparently had side effects that I didn't notice until I was getting the windows build into shape. At first it made no sense, but after some sleep and a walk I realised what was actually going on and was able to easily fix it. However a variation of the crash also happened so I am not sure I have even fixed the original crash...
Over the next week I was going to clean up a few more issues with the windows builds (store and standalone) and see about getting the windows store build ready to launch. And get a gameplay video together; it is the most substantial thing for launch left, I think. Also going to do at least two more rounds of play testing since I don't have a good sense of my most recent relevant changes (a playtest was delayed since I was out of town and ended up not being able to set it up remotely...)
Oh ya, and tentatively aiming to launch by the end of the month. Ideally May 17th.
