Related to the problem I mentioned in the other topic (of a pirate I cannot catch), I noticed when chasing him that sometimes he disappears... He is just, gone.
Sometimes my fleet STILL keeps chasing him, and even engage in battle... I just see the fleet moving by its own and suddenly the battle message.
So the first question is, why pirates disappear like that?
The second question is: why sometimes I can right-click like mad on him even with my ship on top of him and still cannot attack? Sometimes I can attack, sometimes not, the only consistant thing is that seemly if I attack a pirate with convoy "A" and it flees, I cannot attack him with convoy "B" when he shows back on the map, I have to attack him with "A" again.
