2. Action bar. I set up the action bar to have all the fish on it
I just tested the catherby banking again. It successfully got to the bank, then stalled for a good minute running commands "finding best bank", then "best bank found" or something like that while the bank window was open, then after it finished, it deposited everything before stalling again at "bank open. closing." I left it on for 3 minutes before stopping the bot.
I also went back to menaphos and tested the dropping again. This time, I let it set up the action bar on its own, and it stalled, saying "holding drop key based on player sense" and key released 1, 2, 3. I let it run for 5 full minutes before it stopped itself with the idle timer. Oddly enough, I was testing swarm fishing, and it worked for dropping sailfish. It didn't try to drop any other fish, and I hadn't chosen to drop any fish. Very strange. Something worth looking into.
