How to reproduce

AI attempts to use a block that is less than 1 block high to path over a wall or obstetrical

This is happening while creating a build using schematica. There is some snow on the ground that is placed as part of the build. The AI places the snow then attempts to place more snow to use to clear a wall or ascend to another part of the build but it is not high enough to follow the path and the block that is now 2 layers of snow high is now invalid for the schematic. Because the block is now invalid the AI destroys the blocks and tries again and gets stuck in a pathing loop.
