text_A: Witnessing many of his satraps and military governors misbehave, Alexander executed several of them as examples on his way to Susa. As a gesture of thanks, he paid off the debts of his soldiers, and announced that he would send over-aged and disabled veterans back to Macedon, led by Craterus. His troops misunderstood his intention and mutinied at the town of Opis. They refused to be sent away and criticized his adoption of Persian customs and dress and the introduction of Persian officers and soldiers into Macedonian units.
text_B: Do Alexander's satraps and military governors behave when he's not on a trip?
NO.
