From some quick testing on PTS I got back only 25 crystals (in line with Rob Garrett's clarification on the forum recently) but I also got none of the upgrade mats I used back, which seems to directly contradict the information from the stream.

@ZOS_GinaBruno - any chance of clarification on whether this is a bug on PTS or a reflection of the intended system? If current PTS is the intended version will drastically reduce the usefulness of the system, particularly for jewellery where the cost of upgrade mats is so high.

Hello again.

We have another update regarding details of the Item Set Collection system. As many of you know, shortly after the end of Markarth reveal event this past Saturday, we posted a correction about a statement made on-stream regarding Transmute Crystal refunds when deconstructing items.

Well it turns out that wasn't the only detail in need of correcting. As a number of players have already discovered on the PTS, deconstructing a reconstructed item does not refund the full amount of booster materials either. It works the same as deconstructing any item: You have a chance to get a single booster material back, and that chance can be improved by investing in passive skills within the crafting skill lines, but it won't be a full refund.

This behavior is intentional, and it will remain this way when the Item Set Collection system goes live with U28. The reason is we anticipate full booster refunds would quickly lead to widespread “booster recycling”, where players would use deconstruction and reconstruction to simply transfer full sets of boosters between item sets. In that scenario, when a player achieves a critical threshold of booster materials there becomes very little incentive to acquire more. The more players that achieve this threshold, the less value boosters represent within the game economy. Devaluing booster materials was never a goal of the Item Set Collection system.

My error in misrepresenting this aspect of the system during the livestream was unintentional, and simply a case of miscommunication between myself and the team prior to the event. But that doesn't change the fact it was a misrepresentation. We strive to present honest and accurate information to players, and in this case we failed. For that, I want to apologize to the community and express our commitment to do better during future reveals - because there’s some really cool stuff coming in future reveals!

Thank you again for your support.
