Needs a rebase :)

[connorshea]

Looks like flaky tests, we should really merge hotfix into develop so develop PRs won't suffer from these as much anymore.

[Dillon-Brown]

@connorshea Agreed. It looks like there are only 81 files conflicting so it shouldn't be too difficult. I'll look at putting up a PR.
