Nope. I even tried to reinstall all mods and install them in the most "reasonable" order - no. Something has problems with hte SwashImoen component, but maybe I'll try it again - any instructions?
It's not a matter of "most reasonable" order, it's a matter of *messed* orders.
I think the following might have happened.
You install Refinements, which creates many invisible kits. You start a new game. The BALDUR.BCS script, updated by Refinements, notices that in party there is a Swashbuckler, dualled to mage, not yet reactivated.
So it applies a new, invisible kit to Imoen, equivalent to the Swash but with a few technical differences. Let's say this kit is placed in position 41 of the KITLIST.2da.
Then the game immediately autosaves.
Then you exit the game, and do some mess with other mods (you mentioned upgrading Tacticts for instance).
When you reinstall stuff in a DIFFERENT order, that new kit used for Imoen might go in a different position, for example, 43.
BUT, your savegame still points to position 41, and who knows what the hell is now placed in position 41.
If this isn't the problem, then I'm clueless again.
It should be a mod that modifies scrolls (other than Ease of Use) or one that modifies Imoen in its turn. But *you* should know better what those mods do, since you have installed them
