Hmm. It still happens for me every time I do this:
Launch the game.
Log into Character 1.
Launch the bot.
Start and stop the bot to confirm it's working.
Log out of Character 1. Leave the game client opened.
Log into Character 2.
Attempt to start the bot. Parsing hotbar error.
Close and relaunch the bot. Attempt to start the bot. Parsing hotbar error.
EN Client. Windows 7 64bit.
The workaround for me right now is to close the game client entirely when switching characters.
