[3.3.3] Modded trait disappearing on save game load

[Anthropoid3]

I'm trying to figure out why a trait added by a mod keeps disappearing when I load a save game.
So far, I've seen that:

1. The game saves the trait (i.e., I can find its ID in the save file)
2. It loads the trait - it is listed in setup.log, with the same ID as in in the save file
3. The trait is not there after the save game loads

I recall having a similar problem when I tried to do some modding myself a few years back, but I didn't find a solution then either. I have no issues with other mods that add traits either.
The only potential problem I've seen is that the trait in question has potential = { always = no } in its definition, but AFAIK that should only affect random assignment?

Does anyone know how to tackle this problem?

Characters must meet the potential block for traits on save game load. If they don't, they lose traits. This is hardcoded, so you may want to add a check for the trait in there. That way, anyone who has the trait can keep it, but no one else will get it, beyond script explicitly handing it out.

Thank you! I replaced the potential requirement with random = no, which made the trait work as intended. I guess the Wiki was incorrect on this subject then.
