Map Crash On Buying Store Open

[Dragonis1701]

When I try to open a buying store, my map server crashes giving me the error:

---------------------------
Microsoft Visual C++ Runtime Library
---------------------------
Debug Error!

Program: ...s\User\Desktop\Jordan's Folder\Backups\rathena\map-server.exe
Module: ...s\User\Desktop\Jordan's Folder\Backups\rathena\map-server.exe
File: c:\users\user\desktop\jordan's folder\backups\rathena\src\map\clif.c
Line: 16826

Run-Time Check Failure #2 - Stack around the variable 'buf' was corrupted.

(Press Retry to debug the application)

And the code it is pointing out in clif.c is:

void clif_buyingstore_entry(struct map_session_data* sd)
{
    uint8 buf[86];

    WBUFW(buf,0) = 0x814;
    WBUFL(buf,2) = sd->bl.id;
    memcpy(WBUFP(buf,6), sd->message, MESSAGE_SIZE);

    clif_send(buf, packet_len(0x814), &sd->bl, AREA_WOS);
} < Line 16826

Any ideas? I have no idea why it's doing it.

Figured it out. Turns out if your Message_Size was larger than default, 79 + 1, it crashed your map server.
