I tested with Chrome Version 68 and the Bot did not work. Not sure yet if the change was in the browser or the game. I will take a closer look this week.
EDIT:
I had a closer look at the problem: The old method of reading information from the website does not work anymore. This will need some work to adapt it to the current version of the game.
I will fix the automatic farming next week.
EDIT:
There is now a fixed version of the bot that works with the current version of the game. You can find it at Farm Manager - Tribal Wars 2 Farmbot (old version from 2018)
EDIT 2020:
Newest version of the farmbot, introduced 2020: Farm Manager - Tribal Wars 2 Farmbot
