I was playing the Minecraft 15th Anniversary map (mode default adventure mode), I didn't touch the settings of this map, I played well in front, through the adventure portal, playing the jungle temple monster game, the game provided me with a set of armor, shields, bows, arrows, iron swords, these props, the first four are normal, the iron sword is buggy, I tried to hit skeletons and zombies with an iron sword, and found that there was no damage, and I hit skeletons and zombies with my hands, and there was still no damage.

I tried the conventional way.,Exit the re-entry world.,Exit the re-entry game.,The computer also restarts.,The world template is unloaded and reloaded.,It's useless.,The iron sword problem is still there.,No damage to monsters.。
