It has had a negative effect though.
According to original post, 3 crystals are available weeks 1,3,5 and other 3 weeks 2,4,6.
The system was already flawed in that it was impossible to buy all 3 of the crystals that are available weeks 1,3,5 as it took 2 weeks to get enough dark artifacts. But by telling us that we could buy the same crystal multiple times, only to find out that it is not true, makes it even worse. If you bought a crystal in week 2 (like I did), you then wouldn’t have had enough crystals to buy a crystal week 3. Which means you can now only buy 1 of the crystals that was available weeks 1,3,5. If I had known that you could only buy one of each, I would have purchased a crystal weeks 3,5,6. Getting 2 of the crystals in 1st batch.
If you aren’t gonna let us buy more then 1 crystal, make all crystals available at all times.
