But why still happening? You'd think by now developers have enough history to know how to code these in a workable manner.
When those power based ones come out I get excited since it's a good excuse to try a new character, but without it working takes the extra incentive out.
Its still happening simply because the daily challenges are new to the server side code and are still buggy. You have to remember that you have server side storage for your profiles stats, if its not collated and stored properly, you get issues like this. To be fair its pretty easy to make a mistake with these kind of changes, as it involves a fair bit of code to make it work.
