GetMessageOrigData(MsgMsgId) returns the current message ID instead of the original one

[Nord1cWarr1or]

Summary

GetMessageOrigData with MsgMsgId returns the current message id (getId()) instead of the original one, breaking the native's contract ("Gets the message data original value in the current game message"). All other Original branches use the original getters correctly.

Evidence

reapi/src/natives/natives_hookmessage.cpp (function GetMessageOrigData):

case IMessage::DataType::Dest:
    return static_cast<cell>(g_activeMessageContext->getOriginalDest());   // OK
case IMessage::DataType::Index:
    return g_activeMessageContext->getId();                                // BUG: current id
case IMessage::DataType::Origin:
    *(Vector *)getAmxAddr(amx, params[arg_value]) = g_activeMessageContext->getOriginalOrigin(); // OK
case IMessage::DataType::Edict:
    return indexOfEdictAmx(g_activeMessageContext->getOriginalEdict());    // OK

The correct getter already exists in the interface: virtual int getOriginalId() const = 0; (include/cssdk/engine/IMessageManager.h, IMessageContext).

Repro (Pawn)

// inside a RegisterMessage callback (pre):
SetMessageData(MsgMsgId, 999);
new orig = GetMessageOrigData(MsgMsgId);
// expected: original message id; actual: 999 (the modified value)

Suggested fix

case IMessage::DataType::Index:
    return g_activeMessageContext->getOriginalId();

Environment
