For me it is any that have to deal with time of days because the one in Thanland Central that requires a dust storm at a certain time of day did that work when I was in that time of day with the dust storm. The ones you can get with any weather and any time are working just fine though. I use Steam for the launcher, standing directly in the vista during time and weather required, do lookout, pray, or sit and it does not work. (I said those because those are the ones that were needed for the ones I did.) None have worked.
