I have currently completed Season 1.5 Goals as shown here:
However when attempting to claim either of those Goals, I receive the following error:
I have completed several other Goals related to Gear, Spells, and Skirmish Battles Completed and was able to claim those rewards. Only the minion Goals have been uncollectable so far.
Thanks for sharing, was wondering why I hadn’t run into this but you’re right it seems to just be Minions so far!
Just in case as this occurred later and is related;
@Sibelios were your Minions rewarded in the cache or bought from the rewards tab, or both?
