Greetings, all.
I was just checking over some code in YAAC (unfortunately, _after_ I posted build 205 last night), and discovered there is a bug in the OpenStreetMap tile download code when using an older version of YAAC. Even though the last few versions of YAAC will display the older snapshots of OSM imports I keep available for backwards compatibility, they still will only download the latest snapshot (regardless of what you select), which may not be compatible with the older versions of YAAC (which is why that check exists in the first place). There is a minor map file format change in build 205 that was used to create the map tiles I posted this morning from the December 23rd OSM snapshot, so if you download fresh tiles, you will need to be using build 205 to read the tile files successfully.
So please avoid doing map downloads until you upgrade.
Sorry about the inconvenience. I will have this fixed in the _next_ next build of YAAC, but that doesn't help anybody who's still at an older version. I will tweak the website so the September 8th snapshot will be current again.
