Trackster's Shard lineage support disconnect you to the login screen

I uploaded the video to reddit (don't know how to do that here).

Basically after fighting with monsters for a while using Trackster's Shard, I got disconnected from the game. This is 100% replicable too.

I am 90% sure it's the interaction between Trackster's Shard and Midnight Zenith (from Eventide Petals) that is causing this. Because when I took off either of them the problem was gone.
