@turtletank, saw a weird issue. Not sure if it is a one-off or what, but something happened and ADBTuner thought that all tuners were full when they were all open. I traced it back in the logs to something that seemed to start the day before and went on for 16 hours:

It didn't matter the method or what I tried to tune to, it was all the same result. I only fixed it by force restarting the containers, which had been running for 15 days at that point.
