The lfm panel gets it correct. Given that, is it truly difficult to fix completion times on the xp screen.
This has been happening for months if not a year now.
Please consider adding in a 'seconds' component as well if it's not too much trouble. If it is trouble then the lfm panel's "adventure active" timer being pasted into the experience sheet instead is perfectly adequate.
Competitive speedruns are important nonsense that flesh out games. I miss these in DDO.
