Sometimes the raid gets stuck and you are not able to forfeit the raid either.
In that case, click forfeit, open your console player.placeatme XX005E2C
This will spawn a fiend and should solve the issue. Replace XX with the mods load order in hex (or open console, click the watertank and write gbo and take the first two characters) For example:player.placeatme 13005E2C
