Building Gadgets Version
Building Gadgets 2 v1.0.5 (Modpack: FTB Presents Direwolf20 1.20 1.4.0)

Describe the bug
Using the exchanging gadget to exchange blocks when used on the same type as the selected block type won't affect blocks around it even if range is big enough.

To Reproduce
Steps to reproduce the behavior:

1. Place a 5x5 square of dirt
2. Replace the middle 1x1 with sand
3. Set the chosen block of the exchanging gadget to sand and the range to 5 (Fuzzy and connected area doesn't matter)
4. Try to exchange the blocks by clicking on the middle (sand)
5. Verify the dirt is not exchanged to sand

Expected behavior
The rest of the 5x5 should be exchanged to sand (this was the behavior of Building Gadgets 1)

Yea I think I'm fine with that change :)
