A few errors that I've run into (w/ error messages)

[Ryah]

## Specs: Node Version: v6.9.5
Server Version: CraftBukkit 1.11.2
OS: ElementaryOS Loki (based off of Ubuntu 16.04).

I finally got the bot working, but there are a few crashes that I've run into. Here are the commands I've done and the error codes that comes with them. I can provide a video if needed:

1) Anything building related only places one block and then freezes:

For a test, I placed 6 blocks down with the bot watching me, then stopped watching and asked for it to replicate. It placed down one block, but outputted this to the terminal. It never displayed any chat messages about it completing the replicate task.

replicate

I'm going to achieve task ["replicate",[]]
do build r-1,0,-4 then build r0,0,-4 then build r1,0,-4 then build r-2,0,-4 then dig r-2,0,-4 then dig r-1,0,-4 then dig r0,0,-4 done

2) build shelter, replicate, or anything that has to do with building on Snow

/home/unity/rbot/node_modules/minecraft-protocol/dist/transforms/framing.js:112
          } else throw e;
                 ^

3) down (or anything that involves breaking blocks) (temporary fix is to comment out lines 17-50 and 96 in /lib/Inventory.js and also comment out line 146 in /lib/stringTo.js):

/home/unity/rbot/lib/inventory.js:18
    var okTools = block.harvestTools;
                       ^

TypeError: Cannot read property 'harvestTools' of undefined

    at Object.stringTo (/home/unity/rbot/lib/stringTo.js:39:8)

4) come command just doesn't work. Bot says it accomplished task but doesn't move.

5) Anything with the repeat command just repeats a blank command over and over until I force kill the bot.

6) get block (grass in this case):

/home/unity/rbot/lib/nearest.js:39
	return blocks[blockName].id;
	                        ^

    at stringToAbsolutePosition (/home/unity/rbot/lib/stringTo.js:105:2)
    at stringToPosition (/home/unity/rbot/lib/stringTo.js:121:7)
    at stringToPosition (/home/unity/rbot/lib/stringTo.js:118:72)
    at /home/unity/rbot/lib/stringTo.js:39:119
    at /home/unity/rbot/node_modules/async/lib/async.js:356:13
    at async.forEachOf.async.eachOf (/home/unity/rbot/node_modules/async/lib/async.js:233:13)
    at _asyncMap (/home/unity/rbot/node_modules/async/lib/async.js:355:9)

7) toss command doesn't drop anything but the bot still thinks it completed the command (I think the bot can't see it's inventory?)

I'll update this issue if I find more errors and/or temporary fixes.
