Checked for objects in the way. could not find any. also removed the building and reloaded. By abnormal input i mean, set a guy to, teach pick up a cereal seed, when i go to plant it will not plant at all if i do not move to a space with left click and plant after. Moving before planting instead of directly planting allows him to plant a seed but only one, then he takes a trip back to seed pile and plants one near the spot but will not plant outside a 3 by 3 space. This has been the only time teaching has been buggy for me.
