Hello, re. the Gutter supplies factory:
1) click on ingredients
2) click on "In the Gutter Supplies Factory you can make:"the image of the "gutter with downpipe" is not showing.
I cleared memcache and after relaunching the game the image is still not showing.
I use Google Chrome.
Moderator note: this issue has been fixed
