"Cryptowest" is a loser. I've worked with so called "developers" like this before. They are fat, lazy and have almost no actual programming skills.
Most people think that developers have no social skills but that's entirely not the case. I for one have to filter all the technical details out and put it in words that people with little or no technical skills can understand. This development team did nothing of the sort. In fact there was little to no communication on their end. They were just stringing along pool owners and miners and wasting their time. "Bugs" in the software that are overlooked can usually be forgiven by the community. However for this to take place there needs to be a strong open level of communication which was simply not present.
The only clear path that I see is to fire the entire development team. Start over from scratch and try to savage the reputation of the coin. Even though I am not an IPO holder, you could further restore confidence by returning all money that was invested in to the coin.
