I have built Curio Shop, which is supposed to generate a random creature part every turn in the stronghold treasury.

However, after a side quest updated and my party gained 365 experience, I went back to my stronghold to check the treasury and could not find any creature part in it.

Am I missing something?

== Update ==

A task updated and my party gained 340 experience, but still no creature part in the treasury.

Some information on the internet suggest that small amount of experience does not trigger a turn.

That's true. After my party gained a larger amount of experience, creature parts started to generate.

The calculation, as usual, is weird, see here: https://pillarsofeternity.fandom.com/wiki/Experience_and_advancement#Quest_experience
Scroll until "Stronghold turns".
