Adventure mode
Hello, and welcome to the Minecraft wiki. Regarding your recent edits on Adventure; not being able to break or place blocks in Adventure mode is intentional, since the purpose of Adventure mode is to prevent players from breaking/placing blocks (useful for user-created adventure maps and servers). In the Java edition, you can also use commands to give blocks that can only be placed on certain other blocks, or tools that can only break certain blocks.
In addition, the Minecraft wiki doesn't list known bugs in articles as some other wikis might; instead it provides a link to Mojang's bug tracker and bugs should be listed there instead. Let me know if you have any questions. –Sonicwave talk 08:13, 3 January 2019 (UTC)
