Build: 1.10.8 4262 Mode: Creative/Survival Mode: Single Player/Multi Player Reproducibility: Always Severity: Minor Type: Block Placement Summary: One voxel on the large constructor model allows a block or device to be place there, but this block is destroyed when upgrading it. Description: You can place a block or device on the open corner of the new large constructor model in the open area above the control panel. However when you upgrade the constructor to an advanced version the block is consumed by the larger constructor model. No upgrades should ever delete a block or device. Steps to Reproduce: Place a large constructor Place a 1x1 block (or larger) that occupies the space above the control panel Upgrade the large constructor to advanced using a multitool. The block you placed will be destroyed. Downgrade back to a large constructor to verify it is gone and not just obscured. Screenshots: Large constructor with a block placed inside of it before upgrade, after upgrade, and after downgrade:
Generally I would say this behavior is sensible Everything except for placing a block inside a constructor.
