Yesterday the Christmas Update was released alongside with 1.11.
Naturally, as it was such a huge update, bugs were expected.
All of the report bugs have now been fixed.
If you come across other bugs, please make a bug report post!
Regarding Heirloom Fishing Rods. Mojang made the max enchantment for Lure 5 now, that is the reason for h2,h3,h4 fishing rods not working.
We will allow you to refund your heirloom fishing rods soon as a result of this.
