Fishing boost end, nerf or something?

What happened to fishing?
I've been fishing in the same spot while afk for weeks now and always ended up with tons of [event] message in a bottle so I guess that event ended?
but in that case what happened to relic drop rate? after 1 night I used to have 40-60 relic shards in my inventory now even after using my entire fishing rod durability I only get 8-12.
Either something ended, the buff doesn't work or it was nerfed?
If anyone knows what happened, or you also noticed a huge drop in fishing loot please let me know

 

The event also boosted relic shards. The event is now gone. Also is increased rate of relic shards. Drop rate is now back to normal again.
