I spent alot of rosterchests trying to get Harmony Shards and other tier 1 honing mats on my alt - Namoor. But at some point the game graphics froze with the spamming of “harmony shard (300)” etc on the screen, and no harmony shards or other mats ever came to my char. I could not selfie it, as selfie mode was not available where i were (just after using a vern pass and ignoring the tutorials) - but i have pictures of my screen on my phone if you need.
Basically i lost a fkload of harmony shards there or so - and my frustration has no end…
