[quote="Firebrand":2eq0rkic]Maybe what you experienced with the intelligence points was a bug in the game, it didn't limited the top limit of the attributes, but it couldn't handle more of a certain number, so when you save, the game tries to place this number on the memory and crashes (very technical stuff, I know <!-- s:P --><img src="{SMILIES_PATH}/icon_razz.gif" alt=":P" title="Razz" /><!-- s:P -->). For the next version each class might have a limited amount of each of the skills (even those that are greater by class).
I am not that sure this can be. Maybe I do not know something about engine, but programm cannot crash if too large number is stored into variable and variable is stored in a file. Because - to store that number variable already must be of appropriate size and thus it is always stored the same way, whether it has value <= 255 or larger.
For example, if you have 2-byte variable, and there's a number 100 written into it, it still will be stored in 2 bytes as 64 00 (i.e. 100 in the 1st byte and 0 in the second)
