Update Issues

Versions may not be accurate
Some snapshots/versions seem dependent on others. Example: snapshot 12w47e-49a and release 1.7.3 seem reliant to make 1.7.4 to work. I've noticed some reported bugs (I can't specify, I've only tested a few) have been fixed.

You can fix this manually by updating in order and not skipping snapshots or releases. This would be the root for certain bugs, please make sure that full updates aren't reliant on others.
