Plot stopping issue, possible bug

[mota]

I dont know if this is due to something I am doing wrong or if its a bug. I have exult rc1. This is in serpent isle, right after the dinner with the coucil of mages. I speak to Pothos, and he tell me to get him the bloodmoss, and he'll tell me his secret. I get the bloodmoss, but when I go back to give it to him, he wont take it! When I speak to him, he can sell me reagents, and tell me about my stoneheart, but nothing about the bloody bloodmoss. This is a total plot stopper, any suggestions?

Did you get the bloodmoss from the swamp at the southern most tip of Serpent Isle (there are a couple of monolith)?
Do you have a savegame just before you talked to Pothos? Please send to me.

Well, you know it's not a bug. I tried and it works. But to make it
work you need to talk to someone else before. Someone who gives
information about Pothos "dirty secret".
