Fantastic bot, works exactly as described. There are a few things that easily flag players that use this bot though.
1) The log drop locations are always the exact same spots. If the tile click locations could be more randomized around a single tree, when using a single tree, it would look less like a 100% efficient 1.5t bot and more like a human player using it. When people see logs posted in exactly 2 spots per tree and there are hundreds of logs, you are very likely to be reported and receive a ban.
2) When the bot cycles between two trees for the 1.5t, if one of the trees gets cut down, it will continue to use the cut down stump as a part of the 1.5t cycle. The message of not having a spade being spammed in the chat is an irregular action for a regular person, this will get you flagged by the anti-cheat itself, and will get you banned. Realistically the bot should check if the tree still exists during the 1.5t cycle, and if it doesn't it should change to a single tree 1.5t cycle.
Overall I used this bot for over 6 hours with no issues at all. I had a high set AFK rate to reduce the exp rate, hoping it makes it look less suspicious, but who know... I hope some changes can be made to accomodate the issues above, otherwise it is a very reliable bot for any users looking to erase the 200 hour woodcutting grind in one day.
