I was playing on my Minecraft world, trying to find some diamonds, and I came across your app, so I used it on my java Minecraft world, in 1.21 and I typed that in. I typed in the correct cords, and all the things, so when the cords popped up for the diamonds, I immediately went to go dig them up bc they were close and surprisingly under my base. Little did I know, this would lead to my soon 5 demises. So I’m digging down, and when I get to the cord saying where it was, they weren’t there (I know I typed in the seed correctly, I quintuple checked it). So I dig down a little more, thinking maybe it was at -10 instead of 10, but when I dig down, there’s this massive drip stone cave filled to the brim with zombies. But before I can do anything, the block below me breaks, and I land on a stalagmite. Dying. When I go to try and retrieve it, I die again and again. In the process I lost most of my loot, along with a stack of iron ingots.
TL;DR, died using DiamondFinder, and lost almost everything. Not worth it.
