Isolation Vault Issue - Cortege parts seem very rare to drop

[ZephyrGod]

I've completed around 30 T3 isolation Vaults (  basically grinding 4hr every days since the major update).

Problem is the loot table is very dilute and the Cortege part seems rarely drop . So I don't even complete a set to craft yet after more than 30 hr of grinding.

For a long mission of 30-50 min, this is huge pain to do it over and over.

Can't the drop table be changed ? I wonder.

 

Not counting , there are more and more bugs even after so many hotfixes. Which lately makes the grinding even more frustated with around 30-40% chance to get a complete full T1-T3 run without a bug.

I'm having the exact same problem. TOO many bugs and no Cortege parts. Surely they should be tradeble since the other Necramech parts are.
One constant bug is when you walk through the Vaults door after you input the code, the screen goes dark and 70% of the time end up reset outside the door (like when you fall into an area you're not supposed to be in).
