Crew Layabout (Passive) and Crew Layabout (Grey-shirt Old) do not stack for Skill Points given to Allies, but do stack negative Repair Speed and Skill Loss. Unsure if Repair Speed is stacking.

Opiate Addiction and Chem Addiction Resistance once reaching 100% Resistance or beyond has its affect cancelled out. La Resistance (Passive) Sailor With No Name (Gunslinger Old) for example. I suggest capping both Resistances to 99% if possible.

Tandem Fire (Gunner) and Tandem Fire (Soldier) do not stack with each other to net +55% Turret damage Boost. If I may, I'd like to request that when you have both Talents equipped, you get two icons, indicating that both effects are present.

The Description of Bootcamp (Soldier) needs rewording. I assume it is identical to Bootcamp (Passive) - Gain an additional 50% experience, until you have obtained 5 talent points.
When you have 5 or more talent points, gain +15 Bonus Weapons Skill instead.

Implacable (Enforcer & Warden) Revive Affect activate in the same instance, making choosing both redundant. Recommend either both effects stacking for Damage and Duration, or each Talent offering a charge of use, or allow two instances of use.

Enroll into Clown College (Clown Old) and True Potential (Clown Old) do not seem to be giving their listed +25% Physical Resistance each.

Artisan Smith (Technician) Dementonite Recipes are not present in the Fabricator.

Co-Author (Physicist Old) may need to be reworked as its function is no longer available. I could be wrong.

That is all I could find, if anyone finds anything else, post it here.
