The text of the "No Rest (Cycle) for the Wicked II" Achievement is as follows:
"Accrue isleworks earnings totalling at least 17,000 cowries across a seven-cycle period"

Over the last seven cycles my workshops have accured a total of 19,194 seafaring cowries. Seven cycles of solid work, since my last rest period. However, that is spanning two seasons.

Given the name of the achievement, and the ability to choose when rest cycles are scheduled, I believe the intent is to work the mammets for longer periods between rest cycles. So, I have scheduled out 2 rest cycles, 10 continuous work cycles (between two seasons), and then 2 rest cycles.

Is this a bug, is the text just poorly thought out? If the achievement is actually meant to be "earn 17,000 cowries, within a single season", please change the text to clarify that.

It worked fine for me. its in one season not over 2. I had 2 rest days and got my achieve for them working 5 days. Look at supply and demand and use ur efficiancy bonuses alongside that info.
