I know they are permanent. But it's very hard to make 8k points just to spend it on one thing, know what I mean?

It's only for the elite Perhaps 8k is a bit much, but on the whole, they aren't particularly over priced.

I don't think they're over priced at all. It really is a big permanent advantage.

I agree with you... except for the 8,000 points for 500 turns per hour. It's a huge advantage, but the price is also huge. It'll take me like... wow... 80,000 won attacks and not spending points on anything else (no, don't tell me about the point raffle... it's attractive, but I'm not a suicide bomber haha).

Wow, CK fixed this. Thanks!

Now it's possible to buy those upgrades. (Raising points sequence initiated... please wait)

I've reset my account and bought them in various orders at least twenty times. I believe I've fixed the issue.

The problem was that the point center had no way to know if you'd bought the option before.
All other options used the purchase log to check this.

The options which affected your base variables used to rely on a - largely useless - set of fields in your profile(base_attack, base_hp, etc).
Recently, I removed those variables and cut all reliance upon them(or so I thought).
Now, all effects are +- from your main variables and the base variable are an illusion created by calculating your stats from level + point center changes.
