Never really know with Koei, from limited updates mostly for DLC to actual good patches with various improvements and no real schedule or anything just a pending patch in the Steam client suddenly.
Previous update corrected something regarding a DLC only location and this one has these changes.
- Corrected an issue in which, after applying update 1.02, the Gather Rate for "Effects" on the Guide would sometimes not become 100%.
- Fixed various bugs and defects.
So a problem with the guide and who knows what else.
Fairy Tale, one Atelier game and two other projects from a update in November for what's going on over at GUST but apparently also time for updates to earlier games like this one from early April.
EDIT:
Nice to hear about a possible table update too, guess it's impossible to tell whether there will be more patches or not though even with all other projects GUST are working on.
