EngineMode 2 (recommended): This mode will replace all blocks from hiddenBlocks and replacementBlocks with random blocks from hiddenBlocks

EngineMode 3 (recommended): Works very similar to engine mode 2, but works better with slow connections

Legit player view: Legit players wont notice any changes when this mod is installed (unless they have high ping or modify a lot of blocks at once, eg: explosions)
