Hello,
I don't remember having seen this discussed here, and I can't browse the archive of the forum, which has become quite large (what about a search tag, Cvetan?).
When you change a WP when you are too close of it (within 10mn I guess), the game makes you restart at the position at the last iteration of the game.
I thought that this was a bug, but thinking over it, I think now that it is a feature (undocumented?).
As you know, and unlike programmed heading changes, a WP is guaranteed to happen at the exact date required. So if there is a WP within the 10 minutes to come, the program must make sub-iterations to insure the the heading change will take place at the exact date required.
So if you change the WP once these calculations have been made, the best that the software can do is to restart at the last iteration of the game.
Is that correct? And could the algorithm be improved in that prospect?
