Can't observer while player dying with EF_NODRAW flag

[wopox1337]

When a dead player has flag EF_NODRAW we can't observe him while this player dying.

ReGameDLL_CS/regamedll/dlls/observer.cpp

Lines 31 to 33 in f57d28f

	// Don't spec observers or players who haven't picked a class yet
	if (!pPlayer || pPlayer == this || pPlayer->has_disconnected || pPlayer->GetObserverMode() != OBS_NONE || (pPlayer->pev->effects & EF_NODRAW) || pPlayer->m_iTeam == UNASSIGNED || (bSameTeam && pPlayer->m_iTeam != m_iTeam))
	return nullptr;
