This apply to any mobs that have the ability to spawn reinforcement, including drowned. The problem is that it probably doesn't check for entity type.
Affects 1.14.4
I found out how to do it!! Just go into C:\Program Files (x86)\Minecraft\tmp and rename the .tmp file to MinecraftLauncher.exe. MAKE SURE YOU GET RID OF THE .tmp OUT OF THE NAME!! Then just open that "Application." It'll update and run. Have fun!!

I cant do anything, just walk around and fly; :/
Im having the SAME problem in 1.8 except I have a PC
So, I remembered getting different types of fish from killing guardians, and I did a command block to kill a lot of guardians, but they only drop cod.
I looked it up to see if this is normal but I don't seems to find any result.
I went to do some testing again and apparently rare fish drops only when killed by player.
