## Node Module Patches
Some of the node modules that we depend on have bugs in them. PRs have been submitted but currently you must manually implement these fixes in some node modules:
- In `mineflayer-collectblock/lib/CollectBlock.js`, replace `!block.canHarvest(bot.heldItem)` with `bot.heldItem !== null && !block.canHarvest(bot.heldItem.type)` (line 80?)
