Maybe I'm incredibly unlucky, or maybe the bonus isn't supposed to work in combination with the Geneticist (Inn quest)...

...but discovering specific genes seems to use up vermillion 100% of time, not just 50%. Though the cost is still 50 silver.

vv No problem. Confirmed as working, and thanks for the vermillion.

Thanks for reporting.

You're right, it really was taking vermillion each time. It works like it's supposed now.

Sorry for the inconvenience. We added some vermillion to your warehouse to compensate the losses.
