Tasks Win 10 5* or higher artifacts from stage 10 or above in dragon donjon on normal or difficult mode.

Bug: Artifacts acquired in difficult mode (before stage 10) are not counted towards the progress although the task is harder than the basic requirement (i.e., stage 10 normal mode). 

System: This likely a code issue independent of the operating system (tested in android and pc). More specifically, the IF OR function for the stage 10 requirement is likely the primary source of the error. Instead of a series of if else, this should be a nested condition for the same level for the if argument. 

Note: Similar issues likely also exist in other relavent missions, such as spider or ice golem,
