code disappearing !?!?

i spent around 4 hours last night making my space hey profile, when i woke up it was there on both my laptop and phone, but now half of it's gone ?!? I lost the background image, the running pikachu, the stickers in my about me, my miku dancing in the corner, and some other things. im not even going to fix it atp because i'll just end up re doing my profile. has anyone else had this problem?

its also missing on mobile too
