Mathieu and I will look into this next week.

I think we found the issue with this week's session as described in #172, the issue was the old fixtures not including debug information in the artifact.

The mecenas contract still has an issue, because it uses a comment in the middle of a cashscript line which causes a problem for the Bitauth IDE two way mapping.

This issue can either be closed now, or when the final issue with the mecenas source map is fixed.

Today we also fixed the final remaining issue in the Mecenas contract.
