There are many reasons why:
1. Setting proper rules and system in place, as there will be many submissions which would feature stickfigures from other people etc.
2. Changing the automatic (or so I heard) email system to actually handle the new type of files.
3. Other update shenanigans
4. Personal life and other jobs
5. Dog
6. Working on the sticknodes social media (website, reddit, Facebook)
7. Stickfigure submissions, I’m doing around of 1/3 of just the packs without thumbnails and it’s already a lot. Now put in regular sticks, custom thumbnails, and other 2/3 of packs.

Yea. There’s a lot. If I keep going I might question if he even sleeps, despite it being a common knowledge as to it being a myth.
