I have been tasked with meeting the soldiers and taking over Fort Greenwall. To my surprise, my imperial soldier allies were not at the gathering spot. Furthermore, no stormcloaks were inside the fort either.
As such, I cannot complete the objective "Kill enemies - 100% left", as there are no enemies to kill (except maybe one horse).
I've attempted to wait for 10 in game days, but that did not work.
I have found 3 methods to "fix" this problem.
The first is to go to Riften and defeat the Jarl. A source tells me this might break the next quest.
The second is to use the console command
setcommand CWFortSiegeFort 9000
which will complete the Fort Greenwall quest.
The third is to use the console command
to reset the fort quest and hopefully make it work again.
I would like to know which, (maybe not among these), is the best solution for fixing this bug?
