Dragon Caves problem?

Hi! Recently, I've been making a tile world gen, and all is well! But, I've been trying to make underground dragon caves using these events:

Here's how it works:

It goes through the Array, and finds all the 2's. Then it checks if the 2's are between a certain range on the Y-Axis. If they are, it picks a random number between 0-100. If it is between 0-2, then it sets a 2 to 5. Then from that 5, it makes a 20x8 cave out of 5's. But that doesn't happen.

It just sets any random 2's to 5. Can anyone tell me why this is? Thanks!

I thought it'd be more helpful if I included a pic of the weird caves.

Which tiles are the 5? What's the width of your array?

Hutto The darker stone ones are the 5, and the array is 125x125x1

You need to combine events 50 & 51. You are currently getting one row of 5s, and one column of 5s, not a 'square' of 5s.
