Another odd gameplay problem

[Strategia_In_Ultima]

In version 1.91, which I recently installed, I found no option toggle for "Show ship movement lines" as there was in 1.61. I found this pretty annoying, but got used to it after a while and learned to like it. I don't think that is what's happened to you, though, but I found it to be rather similar.

Its right there, where Grandpa Kim said.
