Yes there is. But i do not think there is a smooth way.
You need UnRen :
You must be registered to see the links
Put it into the base folder and choose option 3 (console)
Start the game and load you savefile
press shift + o to bring up the console
type in the following line and be sure you didn't misspell (casesensitive):
del tell_dean_anna_home
tell_dean_anna_home = Task(_("Tell the dean that Anna comes home"))
call addtsk(tell_dean_anna_home)
- the task will pop up. you can leave the console now. DO NOT HOVER OVER THE TASKS. the game will crash because other variables allready got changed.
talk to dean.
