0.8.1 keeps writing into "version_0" folder instead of creating new version_1/2/3... 
0.7.6 (I believe) would properly create a new "version_X" folder per run, but since upgrading to 0.8.1, it no longer does this.
Here's my logging-related code in my train script, which are then passed onto Trainer:
    # custom logging directory
    logger = pl.loggers.TestTubeLogger(
        save_dir=logging_dir,
        name=args.name
    )
    log_ckpt = pl.callbacks.ModelCheckpoint(save_top_k=-1, verbose=True)
