+Subject: [PATCH] ShulkerBox allow oversized stacks
+
+This fixes PaperMC/Paper#4748 where breaking a shulkerbox in survival mode
+with oversized itemstacks would cause a "chunk ban". This fixes it by always
+creating an itemstack using the TileEntity's NBT data (how it handles it for
+creative players) instead of routing it through the LootableBuilder.
