I came back to Oblivion and reinstalled Francescos, as I always liked this mod.
Now I had been affected a couple of times by the calipers/nvde bandits bug before, but was able to fix it using the reset-loot-tables-fix.
But now I discovered something I hadn't been aware of before.
Sometimes when I open a chest there's a caliper inside.
I never thought much of it and left it there.
Now I re-opened a chest containig a caliper and the caliper had transformed to something else.
Having read a bit about the whole caliper issue, it seems that the script that transforms the caliper to something else sometimes doesn't fire the first time you open the chest.
Has anyone encountered this before and is there a workaround?
It is mostly an inconvenience, but it a bit strange...
