hey @kobegeens, there's a load.js javascript file that loads with the site + saves the name of the current theme to the browser's local storage. Then when that file loads up again (on another page or refresh), it picks up if the local storage value is set and if so, checks if its the cat cafe theme (because the other one is the base theme). If it is, then that theme is selected, otherwise it sticks to the main theme.
mb for jumping straight in, I was lurking and got curious as well :3 - then after figuring it out, thought it'd nice to share c:
oops, they should be fixed now.
