So some weeks ago MA changed the min condition of items from 3% to 0%.
I would have thought it can be done with a single sql query that puts 0 to every "Minimal TT" field. With an access to the database of course.
Would be a quick and dirty fix for now possibly yeah,
Why dirty, it's the only logical way. Uses aren't stored anywhere, they are calculated live as (max - min)/decay, so absolutely nothing needs to be changed other than min tt values.
Another problem is many items are protected from editing, like verified or something, so there is no way to do it even manually for the mere mortals.
I'm pretty sure Min. TT is used in a some formulas and some of them may not like it being set to 0.00.
