If a player forgets a mandatory power or a ship retrieval, can they fix it later?

Question

Accepted Answer

Anyone who notices should remind the player, since the power is mandatory. If the slip goes unnoticed until a later phase, it is too late to go back, though a reasonable slip caught soon after is commonly allowed.
