I have restarted the game and the problem persists. I am playing on Linux.
I hope this is an appropriate venue to report this sort of issues. Otherwise, my apologies.
I think that contacting Playtonic Games directly using the email posted on their website: http://www.playtonicgames.com/contact/
...or posting on Playtonic Forums: http://forums.playtonicgames.com/
...will be a better option, since that way your bug reports will reach the game developer faster :)
