Do you remember doing something specific to get this infinite crate going on? Next patch should fix it, but I'm still unsure how it was triggered, I can't reproduce it.
About the UI on the left, I'm not sure what to do when the list goes off screen. I could try to wrap it up into a second column, but then I feel it will eventually take several columns and a lot of space in the end game of the full version so that doesn't sound great either. Do you have any suggestions?
