This PR addresses a critical vulnerability in the WorldEdit integration component of Slimefun4. The current implementation lacks proper exception handling when setting blocks, which can lead to server crashes, data corruption, or potential exploits when dealing with corrupt tile entities. ## Changes - Added robust exception handling around block setting operations - Implemented proper logging for error cases to assist with debugging - Created a fallback mechanism for when the primary block setting method fails - Added safeguards around BlockStorage operations to prevent cascading failures - Added appropriate documentation ## Technical Details The vulnerability was present in the `setBlock` method which directly accessed block data without proper exception handling. When dealing with corrupt or malicious tile entities, this could potentially lead to server crashes or unintended behavior. The fix implements a comprehensive try-catch structure to properly handle exceptions and provide informative logs. Additionally, it implements a fallback mechanism using Bukkit's native block setting functionality when the primary method fails.
