Version: Stonehearth 0.10.0 (alpha_10_5 3) x64 build - Peaceful Game
System Info: Windows 7 64bit. AMD Phenom II X6 1100T. 12Gig memory. NVIDIA GeForce GTX 680.
Summary: Started playing on a new map, successfully placed and build templates for communal beds and dining hall then attempted to build a road. Successfully placed down planned and built first small section then an error occurred while planning the next section (refer to linked screenshots). Closed error and found I could not continue to plan (with stone texture I wanted selected, the moment I click in the world to place/plan the road piece, the piece fails and the texture is deselected). Since there have been a couple of issues with road building I decided to leave it and move onto another task, however I am now unable to plan or place any structures (including templates).
Impact: Game is now limited to generic/automatic hearthling tasks such as farming/mining/trapping etc.
UPDATE: Upon doing a full system restart, I am able to open my saved game and resume normal gameplay.
