It seems new properties on existing scripts are NOT properly added on existing saves. Say you have script X with A, B and C properties properly filled. Now go in game, save and quit. Next, add D property to the script and fill it in. The CK adds it properly but the game DOES NOT SEE IT. No Papyrus errors logged, nothing at all. Start a new game and the property is there.

So far I've seen it happening with KEYWORDS.

Anyone else experiencing this?

edit: scratch the above, as usual it's just me being idiot.
