Great mod, I like the concept, but your mod prevents the MinersAdvantage mod ability to do pathanation. This feature allows to automate creating a path when one path block is created it can define a with and length, for example 3 blocks wide and 15 blocks long and when making one path block it will automatically create the 3x15 block path.

The issue actually lies with event handling. This mods PlayerInteractEvent.RightClickBlock gets registered before the same event in MinersAdvantage. This is because that mod sets itself to load after all other mods. As a result, the grass block is turned into a grass path block before the MinersAdvantage event fires, and that mod only acts on grass or dirt blocks.

I'll get a fix out that allows MinersAdvantage to fire properly but it won't create a path under a fence gate through "pathanation," that's on the other mods side. You still will be able to create a path by clicking on a grass block under a fence gate though, and it'll even continue with pathanation on the other side (although this seems to be a side effect of the way MinersAdvantage handles the pathanation functionality).

would recommend if you can create the same solution in this mod without replacing the default path it would be much more compatible with other mods. Great idea for a mod.
