[Solved]No mandrake in my world help

[Hakuame]

I have already played with my friend in few dedicated servers that I hosted. When I was a newbie, I could find mandrakes occasionally in the servers that I hosted in the game client. After I learn how to host a dedicated server, I never see a mandrake again. Never seeing one in these dedicated server worlds that I created, neither in above ground or cave.

I followed steps from the pinned posts to create my server. I got the "worldgenoverride.lua" code from the following pinned post.

worldgenoverride.lua with the new post-Caves settings

Following the DST client's world edit GUI, I only kept those lines of code that only use in the cave or the master world. I don't know if I deleted some important codes that use for generating mandrake. However, I do not see any mandrake setting from that post. In the DST client, there is no mandrake setting also, but in DS, you can change the setting for mandrake when you are creating the world.

I am not very sure about it. Is there no more mandrake in DST anymore? Or I missed some codes for generating mandrakes? Or some mods can cause the world not generating mandrakes?

This are my cave and master world worldgenoverride.lua files of my current DST dedicated server. Can anyone help me the check if there are problems in the code causing no mandrakes in my worlds?

This is for the master world.
