Does this happen on dev version?

Upon further inspection, the issue has only appeared on the profiling branch. Myself and the people I asked to test the issue have been using the profiling branch for performance reasons for so long that we completely forgot to take it into account.

I'm unsure of what the severity is meant to be in relation to, but within the category of UAV's this is a major issue as it prevents most of their use.
