My fist day as an 800 vet. I found out that the Dilithium mission is indeed only 500 Dilithium a day and not a 1000.
I kept hearing this 1000 number and you would think that since Dilithium is refined daily, that would mean that you get a 1000 extra a day. But no, the mission has a 2 day countdown, meaning its only 500 Dilithium a day.
I really think Cryptic should put it as a 1d countdown, still at a 1000.
