For more information see here Bug Report Template Build: V 1.12.2 Mode: Creative Platform: Steam Installed DLC: No SERVER NAME: Single Player SEED ID: Unknown If applicable: No CHANGED GAMEBOARDS: Reproducibility: Unknown - a persistent issue for me Difficulty: Hard Type: Setting Summary: Unable to adjust the game in Creative mode Description: When loading the Creative game save game, no difficulty settings can be adjusted. This means that the block restrictions remain. Although you can disable this restriction in normal play and, for example, place 100 solar cells, this is not possible in Creative mode. Only 15 can be built. However, this restriction did not exist in an earlier version. Rebuilding old blueprints is no longer possible, as removed blocks cannot be re-placed. Steps to reproduce: 1) Load the game 2) Difficulty settings are grayed out 3) Building blocks beyond their limit is not possible
Not a bug, Most of the settings can't be changed Best to test such things in a normal survival game and use commands
