I had 54k points. Over a single day it dropped to 6k. Why? With literally 0 explanation it's just gone.
My points
Same
Apparently WN decided they should ‘expire’.
No notification ahead of time so you could get a badge or frame. 31k gone overnight 
sobeitt You guys are discussing your lost points here, but I will be shameless and ask you guys to read my novel. I am a new writer and need support in form of comments and reviews.

I didn’t notice and had 4,500 coins points expired 17 days ago or so . And today I noticed at 700 coin point will expire in 3 days and then 800 coins points will expire 8 days . I’m like why? Why do we need expirations? At first it was just 10 expiring few days . Why do we need expiration on bought coins points?
