Modest flint overhaul

Main Idea of the Mod
The developer encountered a problem with obtaining flint from gravel and is confident that they are not alone in this situation. In vanilla gameplay, you repeatedly dig through the same gravel block until you find flint, ignoring the fact that you've already checked this pile of gravel multiple times and that the remaining gravel simply disappears.
How the Modification Works
The mod divides gravel into two types:
- Gravel that may contain flint (blocks created during world generation or mined with a silk touch tool)
- Gravel without flint (obtained by digging with a shovel or hands) - this type will no longer yield flint after the initial drop
The mod makes flint acquisition more realistic and gives meaning to the Fortune enchantment on your shovels. However, realism comes at a price - if you need more flint, you'll have to go underground and find gravel pockets or river deposits.
Compatibility with Other Mods
This part took the most development time. Adding one new block is simple. But both the new and the altered vanilla block need to function correctly in crushers, mills, and other industrial mechanisms. The mod includes compatibility with important industrial mods (Create, Immersive Engineering, Botania) and some technical mods (Thermal Expansion, Mekanism), but incompatibilities with other modifications are possible.
