Currently Log Pillars only have one build state - when placed they appear fully constructed even though they still require one long to be hammered in to be considered complete. This is minor but can be confusing for new players and is also inconsistent with other blocks. Assuming the dev's either didn't want to create an additional model for an intermediate build state, or couldn't figure out what it should be since it's simply a log that has been honed into a pillar. Perhaps just doing a standard stick outline would be sufficient.
