I have removed the p455w0rd.danknull.util.DankNullUtils class in favor of making the internal inventory just function as a normal IItemHandler inventory to outside handlers. This has created a crash and I wasn't aware the DankNullUtils class was being used.

Reported in p455w0rds-MC-Mods/DankNull#209

Fixed in #265

Thank you for trying to fix; since /dank/null is now a normal IItemHandler; the dependency has been removed completely.

A new version has been merged/pushed to curse.
