alef 0 Posted April 4, 2009 (edited) It happens random running two arma in MP the same host with different system users, that is, different MPMissionCache folders. Edit: I leaved some files opened while running, and the temporary swap file causes this problem. Closing the file before arma packs the pbo, solves it.
