So still at this reading of the CDatastore. I've been studying the Wpp and I've trying to read the packet.ReadPackedGuid() :
https://github.com/TrinityCore/WowPacket...r.cs#L1348
I am just wondering if Ymir chops out the first 12~ bytes of the buffer for the OPcode so the binary read actually starts at pos 12 ?

This is just my attempt at the packed read :
```cpp
static uint64_t ReadPackedUInt64(MemoryReader reader, uint8_t mask)
{
if (mask == 0) {
return 0;
}
uint64_t res = 0;
int i = 0;
while (i < 8) {
if ((mask & (1 << i)) != 0) {
res += static_cast<uint64_t>(reader.ReadByte()) << (i * 8);
}
++i;
}
return res;
}
```
