Small bug, when equipping it or even just scrolling over it on a hero character [skirmisher, templar, reaper etc] it locks onto that armour. Changing armour only shows Pathfinder armour available afterwards.

I'm afraid that's just the way it is, you need another mod that unrestrics customization for the hero classes, i have one set as a required mod for this, but there are others, don't remember of the name of the others though since i only use the one i set up as a requirement.

Is Unrestricted Customization unable to solve this problem of Pathfinder armor being permanently locked to heroes?

A bug that might just be me or others, but the cosmetics are straight up gone and removed from my lists.

The units that had them equipped had blurry, low texture models of them on, and when i moused over anything at all it removed them permanently.I do not know whether or not this is a problem with my game or with XCOM in general, but i would like a fix somehow someway.

[Correction]
This should be my final comment on this, but we will see, things may change.

K, so it turns out deleting the Skirmisher, Templar, and Reaper sections didn't actually make the cosmetics re-appear, I just thought they did because the last time I had deleted them, I had also changed the bVeteran setting for all the cosmetics in the Content INI from false to true, so I did redid that change and what do you know, the cosmetics re-appeared, though I do not know why.

However as an addendum, you still need the [WOTC] No Tech Gated Helmets mod so that the helmets appear without needing a specific set of armor, but otherwise just do what I did above and you should be golden.
