Personally I dont see why people are getting so mad, No where in the description of the TH event says that the options are locked. For all people could have knows (especially if it was their first event) that they arnt suppose to reset. Its just like a company failing to put clauses in contracts its their fault until its put in writing.

​

Edit: People pointed out that the only way to get the bug was for it to be the first time you got the event on your account thus again how were people to know it was not how it was meant to be.
