So I noticed that the Unstable Warp event has the new seasonal legendaries in it. I also noticed that the chests in the shop claim “Guaranteed legendaries for event”.
However (and please correct me if I’m wrong), I’m fairly confident that you cannot currently obtain the new seasonal legendaries from these event packs.
If this is in fact the case, then it is undoubtedly misleading for your players. A warning sign should definitely be added to avoid any further confusion.
