I have reproduced this issue, exactly as described.
Game client: v 2019.02.02
Operating system: Linux 64 bit

It started working again after the servers went down.

I created a second account called Logintest and it worked fine, so it has to be something with my account.

It happens after three minutes of waiting to log in.

I did talk to Halite and it still didn’t work for me. I tried both of the ponies :(

30 PC? If you are running a 64-bit processor, then the game client should be a standard 64-bit Windows version. If you are using something with a non-standard keyboard, then you may need to redefine your keybinds

This issue has been fixed.

Sorry. It sounds like you managed to double up the quest somehow by attempting to use one of the fix options. We don't currently have another fix for that. I would suggest that you either just leave the issue hanging or start over with another pony if you wish to clear the issue.

Make sure that you are talking to Halite, not to Silicon. If you click on Silicon, you will not get the proper dialogue, since you are supposed to be talking to Halite. Silicon starts with similar dialogue, but does not include the options for the Choices We Make, since you are supposed to start by talking to Halite.
I have tested that point in the quest and it worked for me.

Is this still an issue? If so, please provide a screenshot of your quest journal so that we can know which quest you are in.

The easiest way to solve this is to simply go find a couple of other diamond dogs in the Heartlands and take them out until you have enough to complete the objective.

Is this issue still continuing?

Did you have any type of disconnection during the quest?

Did you try going back and speaking to Sunlit Chaser again? Doing that should reset things to spawn the cloud again.

Please check your journal to see if you have any unfinished quests with markers that might relate to Dashing Delano. He's currently involved in Foal Time Student and in the Winter Warm Up Animal help quest..

Any further information on this issue? Is it still occurring?

No further communication on this, so I'm closing it up.

I've implemented a new fix for this issue. Please check with Old Quest Marker Fix. He should have an option that says, "I finished the Magic of Ordinary Neighs, but Parsley still shows a marker "

Since no further comment on this has been made, I'm closing this up.

Gypsum is a long-winded pony. That's the way her character is written.
Thank you for the suggestion, but this will not be changed as it is part of the characterization of the NPC.
