Null posts after submitting

This problem has been reproducible so far on both build 1.1.12 and 2.0.0-CI00020 for me. The steps I have taken to cause the issue are as follows:

1. Create a new user which my script runs under, verified with email.
2. Make them a moderator of the subreddit they run on.
3. Create a link post to the desired content (this returns a null post, even though the post was submitted)
4. Attempt to set a flair on a null post and fail.

Not much information is shown when the error occurs (This is a stack trace from the 2.0-.Net-Core branch):

Unhandled Exception: System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.) ---> System.NullR
eferenceException: Object reference not set to an instance of an object.

However, I know for a fact the post task succeeded because the post exists. I’ve currently altered my process to include a step between the post submission and setting the flair, which simply filters down to all of the posts in the subreddit which were created after or at the time the YouTube video (link I am posting) was created, and then checking URLs to make sure it ended up being posted. However I would like to know why this issue is occurring in the first place.

Ok I found the issue, just a minute

Great thanks! The issue was fixed. I did discover another issue but it is different enough to warrant a separate issue.
