Yeah the flagstick not being allowed to be removed is definitely a flaw that needs to be corrected immediately. I realize it doesnt effect or obstruct the ball when putting but some folks like i always remove it when lining up the putts since the stick can somewhat be an annoyance to the eyes on certain monitors.
This non-removal of the flag will no doubt cost some folks some strokes, birds & eagles.
Hopefully it will be resolved soon.
