That's entirely possible but some of them are weird mistakes to make given Colville's experience and the company's previous success. But equally maybe that is to some extent the cause? It worked before so why change anything or make more effort? If that's what happened then I think it's a bit of a mistake because launching an entire new RPG is different to launching RPG products for 5E.
I know he's talked a lot about his experience in the past, but running the company amidst the biggest release you've ever done could just be whole other level of new for him and his team. I compare them to Kobold Press or Monte Cook Games - they've been around for almost 20 years or more. MCDM's a relative newcomer. Getting some of this stuff nailed down and making it really run perfectly is not easy, and just to add to the speculation, Colville does seem like someone who marches to his own beat so who knows if he's trying to do some stuff differently.
