We had some major chart changes today (17/0001UTC). When I updated JeppTC on Tuesday, both the old charts and new ones were in the chart list. When I fired up JeppTC yesterday, the old charts had gone, which would have been a tad embarrassing had I needed to use one of the "current" charts then, before the change date. After a bit of experimentation, I discovered that if I rolled back the tablet date a couple of days, the "old" charts became visible again. Immediate problem solved.
