I have no idea if this is intended, or a bug, but this ruins the experience for me. With hours into the building the map, suddenly to have a mission failure, because one of the original 3 dinosaurs dies of old-age, with is very frustrating, especially as it's an already completed mission objective, and the dinosaur is easily replaced. There is nothing to state that this is a condition for failure, but worse still, is there's no way to know this is why the mission is failing, without constant reloading of the save game, and being in the right place at the right time. This is why I suspect this failure condition is actually a bug.
Please remove failure conditions on dinosaurs which are no longer part of a mission objective, dynamically assign any future mission to a new dinosaur, put a tracker on screen for this objective, or make it that mission dinosaurs don't die of old age.
