I am on my way back from Sagittarius A (about 100 ly away). Every time I try and plot a route the plot route percentage goes up to 98 or 99 and never finishes. I generally can plot up to 1000 years at a time. The closer I got to SagA, the more the routes decreased in max distance. But now I can not plot any route, even 80 ly. Any advice would be appreciated
