Poor Marceline. She shows up late to the LEGO Dimensions' Adventure Time party, she's a timed Big W exclusive in Australia, and while her minifigure is excellent, many of the units currently available in the US seemed to have shipped with broken toy tags, rendering her unplayable in the toys-to-life game.
Toy tags are the disc-shaped platforms that LEGO Dimensions figures and accessories stand on. For rebuildable accessories, like Marceline's Lunatic Amp, the toy tags are generic and rewritable. Toy tags for figures, on the other hand, are hard-coded, the data unchangeable.
Or at least they are once written to. A number of Marceline sets released last week in North America contained blank tags with no data.
Poor Finn, waiting forever.
I've had several emails from tipsters since wave seven launched last week, alerting us to the issue. When I received my press copy of Marceline on Monday, her tag was blank as well. While it's since been swapped out with a working model via PR, I did start the return process through the LEGO Dimensions support website, who seemed aware of the issue and were prepared to issue a replacement once proof of purchase was received. I have not heard back from LEGO Dimensions' PR regarding a cause or even an official acknowledgement of the issue.
This issue might be why the Marceline Fun Pack has been delayed in Australia. I expect this to all be sorted out once the Fun Pack hits in December.
