- slight transparancy to block preview. Changed - Walls dont try to place at extreme angles anymore. - Lines will now prefer the axis closest to player if there are multiple good options. - undo hotkey is now ctrl-z and redo to ctrl-y. Fixed - undo not going past 2. - not being able to cancel placement with leftclicking when out of reach. - blockstate getting stuck in preview before first rightclick.
