Unknown packet on level up

[Karbust 4727]

I recently noticed that the client closes after the character levels up, but not always, but almost always.

On the client syserr I get different packets, like this:

Unknown packet header: 194, last: 17 75
Unknown packet header: 235, last: 17 75

Nothing reported on the server side syserr.

packet.h

typedef struct packet_point_change
{
	int		header;
	DWORD		dwVID;
	BYTE		type;
	long long	amount;
	long long	value;
} TPacketGCPointChange;

char.h

typedef struct character_point
{
	long long		points[POINT_MAX_NUM];

	BYTE			job;
	BYTE			voice;

	int			level;
	DWORD			exp;
	long long		gold;

	long			hp;
	int			sp;

	long			iRandomHP;
	int			iRandomSP;

	int			stamina;

	BYTE			skill_group;
} CHARACTER_POINT;

I used this: 

 

Any idea? Like I said, it doesn't happen every time, but it happens more times than it doesn't.
