Error with postselection and parallel

[TheIronBorn]

With parallel = 2 and postselection = 0.05 in scenario.txt I get:

Error: == irace == !is.null(.irace$cluster) is not TRUE
6: execute.experiments(experiments[which.exps], scenario)
5: race.wrapper(configurations = configurations[which.alive, , drop = FALSE],
