The problem is caused by a very small error in the script that tells the han plant to regenerate its contents. I've fixed this error, and now your han plants will give you han, as they were supposed to do all along, and Rebis will no longer be so scarce.
This fix comes in two versions:
1. The REGULAR VERSION of this fix doesn't INCREASE the amount of the herb; it merely changes it from Berbercane fruit to the Han fiber that it was supposed to be all along.
This script is called when the plant refills itself, so if your Han plant already has Berbercane in it, you'll need to pick the Berbercane -- to make the plant empty -- before the new script will refill it with Han.
This version of the fix is available below (you have to be logged in to see it) -- it's the one called hemp.zip -- or at The Witcher Nexus.
2. The PLENTIFUL HAN version both changes the refill from Berbercane to the Han that it was supposed to be AND makes the plant give you more Han fibers -- 5 per day. Because you have the Midday Bride to lay to rest and a peace between the humans and the Vodayanoi to negotiate; you don't have time to spend all day gathering herbs.
This version of the fix is available below (you have to be logged in to see it) -- it's the one called Plentiful_Han.zip -- or at The Witcher Nexus.
The han plants call the script that refills them every (in-game) night at 23:00 (11 p.m.), so the new number of han fibers won't be there until after 23:00 the first day that you play after adding this mod.
To use, simply unzip the enclosed file and put it in your Override folder. If you haven't got an Override folder, just make one; it goes in your The Witcher Enhanced Edition\Data folder.
If for some reason, you actually WANT your Han plants to start giving you Berbercane fruit , just take the hemp.ncs file out of your Override folder.
