The other day I was playing destiny doing seasonal quest for my Titan and I come across that send the challenge right after getting the exotic bow for stars crossing well yeah I completed it but it wasn't registering it was telling me I still had to go back in I don't know if it was a bug or an issue but it needs to be fixed ASAP because it's causing a major issue to where I can't complete my seasonal quest for that character and I usually complete all seasonal quest for all three characters and it is holding up my progression I've had to use my warlock doing its seasonal quest completions because of this issue
