What problems I found with Agbot:
Delay: 2.4.4 is fine, 2.4.4 (including 2.4.12b) is slower.
Explanation: I set stay idle when no monster. I stand next to a monster (Hashade) which spawns at the same place. In case of 2.4.4 the console says every second, no monster, and when monster spawns, attacks monster immediately. In case of 2.4.12b, the console says every 4 seconds, no monsters and attacks monster mostly 4 seconds delay, when monster appears.
Other explanation: in 2.4.4 when I use iron skin buff, bot does it "on the fly" immediately picks up gold or attacks monsters after buff. In case of 2.4.4+ after iron skin, bot waits a few seconds.
Bot does not attack monster, only follows it.
Explanation: I found that bot thinks monster is gold and tries to pick it up! (I was watching console ...) As monster moves, then bot follows that monster. This is definitely an error in 2.4.4, I did not test in on 2.4.12b.
