Another setback session, more or less.
The PCs raided the kobold lair again. They found the treasure chest with a note asking for quarter, but the PCs decided that they should just murder the kobolds and take everything. They ended up focusing most of their attention on the common room full of regular kobolds and females. Bloodlust took over, but ultimately the PCs had to withdraw. They went back to the base camp (my version has a base camp near the Caves of Chaos, with a keep being a little bit farther away.) In the two days it took to heal up, the kobolds evacuated their cavern, and the chief took all of the portable treasure. The PCs gained a pitiful 50-some experience each from the loot and killing kobolds.
I feel like the players are starting to get frustrated by the glacial pace of this game. We've been playing since July and only one person has made 2nd level.
Part of the problem is that we only play for about three hours every other week. This is due in part to two of the players having kids who must be abed before they can play, so we start later than I'd normally like.
Another factor is hardware/software problems. We've been using a combo of Discord and Roll20. Discord, for some reason, just likes to randomly stop picking up sounds from the other players, or stop transmitting sounds from me, or both. It happens out of nowhere and then I have to fiddle with various knobs and dials until one of them inexplicably restores my mic's functionality or I start being able to hear the other players again. We lost a good chunk of time on just my tech bullshit last night.
Finally, the players gave up on the previous dungeon without having reached the 2nd or 3rd level, which were the treasure-heavy levels. There were clues to get down there, but in one case I think my clues were too obscure, and in the second case they overthought it and then just shrugged their shoulders and gave up. If they'd made it to the two lower levels of that dungeon, they'd all be 2nd, perhaps 3rd level... there was a flippin' Type A treasure down there.
So, we can conclude that several factors are in play here. It's just a bummer to make such little progress.
