Its just a quick update to fix the worst bugs. I'll probably do a couple more bug-fix updates before I go on to doing walls.
0.42.1 -Added "Shadow Range" option. Affects view distance of shadows, lowering it will boost performance. -You can now add the unavailable red research items to the research queue if its requirements are already queued up. -You can now double-click a character portrait icon to move the camera to follow him. Same as right-click. -Steam version is now DRM free. Lots of people couldn't enter their codes and were having trouble running the game, and I realised it wasn't actually necessary, it was really just a throwback to the unlockable demo version that needed it.
BUGFIXES -Fixed zones sometimes not loading, creating an invisible wall. I think its fixed anyway, hard to test. You may still need to repair the old zones with ctrl-shift-F11 if necessary. -Fixed vanishing craft items -Characters teleporting away randomly when dismantling stuff -Fixed the Stone auto-mine, it was impossible to place.
