Strange traits bug

[bovi]

The "slain" traits, and other oddities, are caused by loading an old savegame with a non-savegame compatible change to the game files. Such as adding a trait or installing certain submods.

@ bovi... what submod? wait... did u mean changing the values on export_descr_VnVs (even without messing the slain trait, could get all way wrong? (confused)

[bovi]

Add or remove any trait, and they all go 52 pickup in games started without that change.

Check this, my favourite.

Spoiler Alert, click show to read: 

This screen is taken from one campaign that I did not restart a new one after I'd changed the ancillary files.

Ancillaries are as sensitive as traits.
Unfortunately, I could not find the picture that Arshak/Arsaces himself was a legion Legate..

Wow. I never knew this bug happened to ancillaries... Better check that Romani campaign quick for more lulz!!

There is no bug. For an analogy: this is as if you changed the kernel (core part responsible for managing everything in the OS) of your operating system to a version which is not backwards compatible on a binary level, then expect your old hardware drivers to `just work'. They won't, they can't: they've been built against the older kernel and expect the older binaries.

That is what Save Game compatible means: your save game is `built' against the data files. Changing the way the data behaves breaks your old save games.
