Can't attack bug or a feature? (Stellaris)

Hello! I have version 2.3.3. Within the Federation are at war with two other federations, manage the Federal fleet. Faced with this phenomenon, attacking the Federal fleet, the fleet of one of the hostile members of the Federation, all as expected chose the Navy, clicked on a strange fleet appeared linear bound attack red, and the status of my fleet is the transition to the appointed place (so many days), and my fleet goes to the opponent not attacking, and he upset me from all calibers. It's a shame though)) despite the fact that even the odds in my favor in multiples. Tried to pause, to give the game to catch my breath and start the process again, does not help, continues the same disgrace. Then after a while suddenly the enemy fleet instantly jumps in an unknown direction, all the staff immediately. And attack bases are normal. Considered the parameters of the alien fleet, like any of the features of ships or admirals there to prevent my attacks, did not seem to feature. Reload the game and it's back to normal, but up to a certain point and again takayazhe nonsense. The toy itself is interesting, rich ratefactor control, multidimensional story, graphics are tolerable, but these are the miracles turn away from the game. Tell me what to do, if encountered. Maybe somewhere new release swing?
