Ranwid encounter Crash-Bug

[Duckmäuser]

I came across a new encounter today where a guy named "Ranwid" approaches me and i have the options to offer gold, a potion or card and get a relic for it, or to fight him. The potion option was to give my fruit juice. So i thought i would cheese it, and drank the fruit juice (which is possible outside of fights) and then clicked the option which resulted in a crash.
