Hello mojang, today I was playing on my survival world and thought that I should defeat the warden. so, i prepared myself a bit and then also found an ancient city. before all this my advancement tab showed that i have defeated 33/36 hostile mobs in the "monsters hunted" advancement. i defeated the warden pretty easily, thanks to my armor. after all this i checked that if the advancement is chanced from 33/36 to 34/36 but, it was still on 33/36. i checked my statics which did say that i have defeated a warden in my survival world. i tried defeating another warden but that still did not change anything. i thought that this is only happening in my survival world and tried killing the warden by generating another world but it was the same case for that world also. so can i get this bug fixed mojang pls?
