FARL 0.3.12

PRE-Release!
There is a bug in Factorio 0.12 causing issues with FARL:
Read before use

• FARL will place rails over water, you can drive on them, but not walk.
• FARL will place rails over/under other entites (assembler, chests, inserters, etc) until it collides with them
• It can happen that FARL goes into automatic mode, causing the "No path" message to appear. Most likely it ran into a tree/stone it couldn't detect. Stop FARL and automatic mode and remove trees/stone or try again

Changes:

• fix error when reversing while FARL is active
• fix rare crash when activating near (~30tiles distance) a pole
