With the release of the new Pharoah’s Quest sets, many people bought the magnets, as they are an easy way to get the more desirable minifigs. However, the magnet figs were glued to their bases.
When asked for an explanation, LEGO said that all magnet figs will be glued from now on. There was a contractual issue with the magnets in the licensed themes and they had to be glued. In order to make things more efficient in production, the decision was made to glue all magnet figs rather than run two seperate magnet lines (glued and unglued). This has caused a lot of consternation in the community.
