Not all the waveforms correctly downloaded #124
Description
When asking for HH* channels for a given number of earthquakes, the SAC saving option only downloads waveforms for the first channel (HHE). For HHN and HHZ, the message: "Sequence item 0: expected str instance, tuple found" appears. I have to select them one by one the channels, which is a real pain.
Can you explain what's going wrong (last week I didn't have this problem)?
I'm running it on a MacOS 13.1 platform, python 3.10
