Can't give the courage potion to Yox

[Akatosh]

Hello

In quest "Master and slave" I found and cured Frederic with a bloodstone I had with me, then he attacked me and I kelled him. After that I found the cave and the Imp, and told him to stay in the cave. Now I have the Courage potion in my inventory, but when I speak to Yox, impossible to give it to him, he just says "No no no, master will kill me" and so on ...

Any idea to let me complete that quest ?

For info, I came back later (several hours) and then I was able to give him the potion while speaking Don't know what changed between the trys. It completed the quest anyway.

Although I never examined it, I think it's a script problem, some code asks for a condition 'too early' and makes Yox 'thinks' you do not have the potion.
The condition check is only ever done again when you leave and re-enter the cave.

Some script code that sets the condition after you crafted the potion seems to be missing or is not executed due to another (buggy) piece of code preventing it.

Quit game & enter again. Works for me. :)
