Bug: when choosing the amount of items to craft ("Produce [X] times"), I click on the cell with the default "unlimited" value. The content is automatically selected, but in most forms it isn't so I use Ctrl + A hotkey out of habit. The value "unlimited" is then replaced by "unli000000ited". Occurs both in Chrome and Firefox on Windows, only when MWITools are enabled.
