Ever thought that what is the point of adding another bar when the animation is at 98% as stated in one of the messages we got here. He is left with editing and rendering the animation.
Also there is could be so many miscellaneous things, such as maybe there is some work on DOL, could also include remaking a few renders like he did for Dylan Amber. There was the mention about players being able to directly play Part 2 from the next update onwards without having to carry forward saves from Part 1. Atleast i remember
Bibifoc mentioning it. There could be some more work too.
Also it is not like the update got pushed back by a month like it happened with v0.130. It is just 3-4 days back. This game is no life saving drug on which are life depends. None of us are that addicted, or at atleast i hope so, that we can't survive a 3-4 days of delay.
