Medical Room, Programmable Block, & Survival Kit Skins Not Persistent
I have noticed that the Medical Room, Programmable Block, and Survival Kit blocks all revert back to the default (dirty/scratched) skin when the game is reloaded. They can be re-colored and re-skinned but they always revert back to the default skin.
-Create Star System survival world.
-Spawn in space suit
-Use creative tools to create a 5 x 5 large grid
-Place Medical Room, Survival Kit, Programmable Block (and reference blocks if desired)
-Recolor/Reskin them (I used the lower right default color, #262626)
-Reload, the skins should have reverted.
I have attached a save that should demonstrate.
