I have the same issue with the Assassin skill, the soldier won't regain concealment , but when the Bladestorm skill triggers, the soldier will conceal if kill the enemy.

Both Shadow Ninja and Ninja Warrior have save issues. After doing some tests, I found out the same skill from Recon Officer is functioning correctly.

Anyone knowing why and how to fix that?

Nope, specs are (almost) always safe to add at any time, provided you had the main Amalgamation Classes mod active already. They'll only show up on newly-rolled characters, though.

do I need to start a new campaign after downloading this?

Hi, cool spec. I have tried it out, I kill enemies that are flanked, but I do not seem to regain concealment?

@wynton Yes, it is needed. My bad for leaving it out. Thanks for the catch.

Is "Primary Secondaries(or TPS)" not required?

@reddsbaron rebuildselectedsoldiersclass

is there a console command to rebuild a soldier using this?

Aaaaand congrats on release again!
