cse_local_slave_create is broken when adding more than one instance of the same FMU

cse_slave* cse_local_slave_create(const char* fmuPath)
{
    try {
        const auto importer = cse::fmi::importer::create();
        const auto fmu = importer->import(fmuPath);
        auto slave = std::make_unique<cse_slave>();
        slave->name = fmu->model_description()->name;   // <----- HERE
        slave->instance = fmu->instantiate_slave(slave->name);
        // slave address not in use yet. Should be something else than a string.
        slave->address = "local";
        slave->source = fmuPath;
        return slave.release();
    } catch (...) {
        handle_current_exception();
        return nullptr;
    }
}

cse_slave_index cse_execution_add_slave(
    cse_execution* execution,
    cse_slave* slave)
{
    try {
        auto index = execution->cpp_execution->add_slave(cse::make_background_thread_slave(slave->instance), slave->name);
        execution->simulators[slave->name] = cse::simulator_map_entry{index, slave->source, slave->instance->model_description()}; // <---- HERE
        return index;
    } catch (...) {
        handle_current_exception();
        return failure;
    }
}

As highlighted above, execution->simulators[slave->name] is overwritten each time a new slave is added.
