I don't know why this error is happening, I have 43 thousand points and I can still level up.
past level 21, you need over 4k Battle points to level up 1 stat from new file. Old file not more than 3K BP. currently at level 28 or 29 and 4K bp says not enough (I'm guessing that old file need more than 6K as he is level 59+)
Have you tried spending the 43K battle points? It seems the more stats you upgrade, the number of points spend increases from 300 to 6K(at level 20+)
I have done it, and it does not give me any error, so I do not know what happens in your game or file that gives these errors.
No errors. Just more battle points needed compared to the old patch updates.
