We don't really understand what's happening in #1561: the prediction starts after the current time of the plugin, which is rather mysterious (I have a hunch that the code that "forgets before" the prediction has something to do with the problem).
By forking the prediction at the end of the psychohistory, I am ensuring (1) that the prediction can be evaluated at times that are covered by the psychohistory and history; and (2) that the management of predictions is better encapsulated in class
Vessel. The latter should ultimately make it possible to compute the prediction asynchronously and address #761.I am going to mark #1561 as fixed for now. Hopefully if it ever comes back it will be clearer how/where invariants are violated.
