Valentine Tips.....
Regarding the first paragraph, that is working as intended.
Regarding the second paragraph, I have no idea. That's not something players will know/be able to help with.

I am not pleased.

Weird. I was able to dismiss an uncompletable valentine tip.

Governments have fallen to the power of social media. Gaming companies can too.
Not when you select them. If you select them, you wont be able to drop it. Even if you reselect a new mission.

You dont dismiss the mission, you dismiss the contact. Even if you have selected the delivery mission and it active you can dismiss it. I've done it with opposing alignments tips about 4 times last night. Contact>Tips> click Investigate > Dismiss
Two possiblities: you need to restart your client? OR since you can only complete like 5 tip missions in a 24 hour period, perhaps the system is not letting you -touch-/change/dismiss if you have exceeded that limit?
So I've been doing Valentine Tips on Exalted on a Hero. I've been getting "Deliver it to" In Grandville, Port Oaks, Mercy Island etc etc. How the in the WORLD can I get to the villain side to complete it?
So I've petitioned it 3times, all the GMs said the samething, dismiss/abandon/auto-complete. Won't let me abandon, dismiss, auto complete. Two of the GMs were able to advance the mission as where I'd still get the credit. The second GM had a great idea, select a new mission and then see if I can dismiss the Tip. I was not able to. The 3rd GM was not helpful, said dismiss/abandon/auto complete it and move on. He said he is not able to Advance it for me, therefore submit it to Senior QA team. I have been waiting for 30minutes for a reply. Are these tips working as "intended" too?
Sorry, but I see a "error" in these tips in the programming and testing part before they were released.
Edit: For my uncle, the GM told him to change his alignment from Hero to Vigilante to complete the Valentine tip. We don't have the time to change our alignment as it takes two(2) days.
