@dwmatiz Couldn't reproduce this so far: in my case the f** draft disappeared completely after the Discard command.
But I know, why you could encounter this:
1. Draft deletion is an asynchronous action. So you may see a draft before it is actually deleted.
2. Sometimes context menu commands don't work due to the Timeline being updated after opening the context menu :-( (need to improve this...)
3. Some months ago I noticed that a draft is not discarded due to some other reason. Please make sure you have v. 43,02 installed.
