To be fair he was (allegedly) injured pretty badly so wasn't able to work for quite a few months.
From memory, if you believe the Dev, he moved into new premises not long ago (before the last update but i can't remember when) so he moved again after the last update. Think the issue was with both air con but also wifi speed.
As a result after the last update he moved premises and then had a major issue with a hot glue gun that badly burnt both hands and effectively stopped work from the last update through to about December and he only got up to full speed in Jan.
I tend to believe him. His general development rate and updates, including length etc, took a noticeable dip for a number of months and then picked up back to where it was previously. Leads to the idea of a complete hiatus of work, for whatever reason, before he started again. On that basis, in my head, this is 6 month update not a year.
He said in his dev post for April 30th that the total update, whilst only being 1 day so i imagine a lot of similarity, was over 3000 renders, and therefore twice the size of the combined total of 2024.
It seems weird that he'd say that and only produce a final update of 1600 renders long.
Guess we'll wait and see
