Had a few issues:
If the chat box isn't open it gets stuck and keeps clicking the "All" chat box over and over.
When attempting to log out for break, it gets stuck and keeps clicking the "X" in the top right corner and never logged out.
All the dropping methods seem relatively the same. When I use "Top-Down" option it doesn't drop down the line from top to bottom like you would expect. It does some random drop pattern from top to bottom left to right. Not sure if intended
