I haven’t spoken with anyone from the LEGO® company directly about this issue, but after reading the various responses to the defective joints in Lesovikk, it seems most of the recent sets with the lime green sockets (the one that often makes up a Toa’s hand) contain ones that were improperly cooled causing them to break upon removal. Ive seen reports that Toa MAHRI Hahli, Barraki Ehlek, and Lesovikk each may have these. Be careful when removing the part, and make sure your eyes are covered and try cupping your hands around the part when removing it just in case something launches off if it does break. The LEGO company is always happy to replace your defective parts .
