Building Gadgets Version
buildinggadgets2-1.0.5.jar

Describe the bug
When filled with dirt and that dirt turns into grass from the surrounding grass block. When you undo it will give the grass blocks instead of dirt.

Expected behavior
It to not silk touch the items it's giving back if changed but returns the original item placed.

Forge Version: Forge - Forge Version: 47.1.3

NOTE ON RUBIDIUM
Rubidium contains code that will crash many mods when used in conjunction with them. Unfortunately this includes Building Gadgets 2. There is absolutely nothing I can do on my side to prevent these crashes. If you're using Rubidium and your game crashes when rendering something, please try without rubidium before submitting a bug report.

Grass is annoyingly a special case - most blocks i'm ok giving back the silk touched version of - like if you were building with redstone ore for some reason and accidently placed a row, I'm ok with the undo returning the silk touched ore. But grass..yea I can see your point :). But if you were building with grass, you'd want to undo and get your grass back, not dirt.

I have to decide if I want to special case grass. The 'undo' method doesn't really track what block state was there before, mostly because it shouldn't matter. If you undo something, i wanna give you back whats really in that spot, not what you placed, so you can't place a diamond block, replace it with dirt manually, and then undo it and get a 2nd diamond block ;).

This might just have to be one of those annoying quirks thats not easy to work around. I'll think on a good solution if there is one, but grass is just weird like that lol.
