Cant do the new missions, because the Trust from Brad is -10 and cant do anything against it. Dont want to restart the game after 70 hours of gameplay. :D

Well in the future make many save files to not make bad decisions. Here are ways to raise trust iirc: Give money to a man in Dorgania’s capital, help person in northeast of the capital, do quest for Queen of Dorgania, say you do not support slavery to King of Dorgania, send slaves to your castle (not dungeon, brothel or anywhere else), i think helping a slave in Dorgania castle also raise it. That’s all i can remember 

Anyway, if you cannot find any ways to raise Brad’s trust then just start a new game. I have “speedran” the main quest in about 1 hour. You only need 35 trust to continue the quest and every raise in brad’s trust is 10 I believe. Btw if you have played 70 hours then I think you can start a new game easily.

If you upload your save somewhere I can edit trust  in debug for you. Alternatively you can DIY you just need VXace and scroll through a bunch of flags until you see it.

I'll take the 5 minutes to do it and upload it back to save you the time. I didn't have that issue but I recall seeing the flag to change it.
