Your limit went down since you most likely hit the cap last week (don't ask me why it works that way but it does). The strange stones are merely a system put in place such that you can still get something even though you hit your cap, and meant to be worth considerably less than moon coins, so don't expect prices between the two currencies to be comparable. To see this, just note that a single mood scroll is even more than a fuku frag.

By not reaching the cap the previous week. Everyone who consistently hits their cap will eventually end up starting each week with a cap of 44k moon coins, and ending the week at 68k. To get a higher cap, you need to NOT hit your cap the week before, so its a counterproductive system that way.

The cap is OAS way of making sure no maxes out any system too quickly. Moon and sun coins are a great way to free farm systems, but without a cap people would max systems a lot faster and we wouldn't have anything to work towards in the game anymore

I mean I have what confirmation one can have without actually seeing the code and what not /: everyone on my server who's been hitting cap each week by end of week starts on Monday with 44k cap, and then it goes up 4k each day to end at 68k on Sunday, resetting back to 44k Monday as long as you hit the cap on Sunday. If you don't hit it, the cap ends up being slightly higher.
