Minecraft Redstone – Maximum Limit of Blocks a Piston Can Push

I have no idea what that message means or why it appears, but I have a strong suspicion that it's a bug. For me, that message just goes away if I keep trying. Currently, Land Marks just generally have trouble connecting, don't work properly, or crash the server. I don't know what's up with that.

What usually works for me:

1. Place 3 Land Marks to denote the rectangle you want. Do not activate them.

2. Right click the one in the middle (i.e. the one that has 2 adjacent Land Marks). It should form a red rectangle.

3. Place the Quarry directly in front of the Land Mark that you just clicked.

If they didn't connect in step 2, try again with 4 Land Marks.

Try the /fill command. If you fill with minecraft:air, the selected region will disappear. Usage:

/fill X1 Y1 Z1 X2 Y2 Z2 minecraft:air

Troubleshooting: if it says "cannot place blocks outside of world", go into the middle of the selected region (do not go IN the selected region, just into the part of the chunk that needs to be loaded). If it says: "(whatever your block fill count is) > (maximum blocks)", start half at a time. If this grammar is incorrect, please edit it.
