You might want to re-read his March 29th report, he outright says he's "been having issues". There's nothing wrong with him wanting to keep personal things to himself, but he clearly broke his word that he'd keep people apprised of the situation.
Not sure if my English grammar is good enough to understand your point. I'm German. If it's something about the used tense, it might escape me.
The way I read his post: He had issues that kept building up, but still thought he could finish in the planned time. Until he didn't. In my interpretation, that point would most likely have been March 29th or maybe a day or two earlier, depending on what happened and if he had more important stuff to do than make a post about it.
The issues of whatever nature obviously started earlier. The question is at what point we expect him to alert people of possible complications.
'I had a huge fight with my wife today, if this doesn't get better we might decide to get a divorce in two weeks and I'll have to focus on that.'
'My mom broke her ankle and got hospitalized, she might get an embolism and die in two weeks.'
...or whatever.
Those aren't great examples, I lack the energy to think of something better atm, sorry. But I hope you get what I'm trying to say.
Without knowing what these mysterious issues were/are, it's pointless to make assumptions as to when WWG should have realized a March release wouldn't be achievable.
I'm not arguing here, as
pinkie96 implied, 'to prevent a shred of criticism to WWG'. I don't know him, I'm no patron of his. I DON'T KNOW IF HE'S BEEN LYING OR NOT. Neither does anybody else here.
I just don't see any evidence, only assumptions and interpretations. And I'm fed up with people always assuming the worst of others. -.-
