In Minecraft 1.20.4, there was an error in the panda model, causing their backs to appear horizontal. However, after at least one feeding, their model will automatically correct completely and appear tilted. And as long as the game is not restarted, the Panda model will not return to its original incorrect appearance, whether you are playing with a different saves or on the different servers.          (Perhaps it's also because I just misunderstood. This may be a bug where the model made a collective mistake after feeding.)   

       原话 " 在Minecraft1.20.4中，熊猫的模型有错误，致使他们的脊背看起来是水平的。但是，当至少喂食一次之后，他们的模型会全部地自动修正，看起来是倾斜的。而且只要未重启游戏，熊猫的模型都不会再变回原先错误的模样，无论你是换存档玩还是换服务器玩。 （或许也可能是我正好理解反了，这也许是个喂食后模型集体出错的bug）"
