I've experienced a minor bug today.
Someone shot drill rocket into the water and for the rest of the game (about 5 minutes) I, as well as my opponent, could hear the drilling sound, which was pretty annoying.
Yeah. Sorry about that. Has come up many times since 0.9.12 release.

For linux, it should be in the Ubuntu .deb already, or you could try:
And for OSX, might be fixed already. Ask koda.
