There is a small bug at line 602.. Don't worry, not really your fault, just an oversight by the dev
Lusteam..
You seem to have fixed an indentation mistake by the dev which would have caused the option "Train" (fairly at the end) to not playout properly, yet by fixing the mistake there is now an if statement with nothing to follow, which causes it to halt on startup.
Only happens when the patch hasn't already been compiled to an .rpyc previously.
To recreate the problem, try the patch on a new install or just delete the script.rpyc
tbh. dunno what
Lusteam even intended for this check, cause in the original the script would have just ended if dexterity_points not 0.. gonna ask him later.. ';P
