Hey guys,
I've been lazy again have not managed my string variables properly.
I.e.: I've created string_vars over the same variable names without destroying (with sv_Destruct) their previous data.
So, I've started to get this:

Loading strings  WARNING: substantial numbers of string variables exist for the following files (may indicate savegame bloat):    kuerteeSimpleVampirismExpanded.esp (157 strings)

I used to get it in my other mods: Battle Fatigue and Injuries, and Alternative to death and reload.
They're easy to do a clean save on, because their data is non-critical to the player's progress.
However, Simple Vampirism Expanded's effects are too important that restarting it from a clean save is not ideal.
(It does have a facility that checks the length of time the player was a vampire and set its effects from that.
But that facility is more so that players can start playing the mod from their mid-game.
Players who've played the mod from start, wouldn't want random effects from that facility.)

What's the best way to remove unnecessary String_vars from the saved-game?
Note that I've already added a sv_Destruct to my script that removes the string immediately after they are used.
However, I can guess that previous string_vars that shows up in the log are from data that's been disconnected from the variable because I simply created new data over the same variable name.

Does this make sense? If so, help would be appreciated.
Thanks!

Don't know if this would work, but what about deleting the function that created these string variables and creating a new function with the same name? If the string variables are linked to the function they should (hopefully) be deleted too.
