After using rerolls and getting into a new lobby you're unable to use rerolls or switch with anyone. The button is clickable but nothing happens. Not sure if this is known bug, and don't know exactly were to go regarding bugs.
On the homepage of the Alpha there should be a picture of an insect on the lower left of the page (I forget which tab takes you to it though). When you click on it that should open a web browser with the Alpha bug report tool. Just fill out the sections with your bug :)
Alpha client is a very stripped down version. There is no rerolling or trading.
