'<class 'Generators.GeneratorsConf.Generation'>' object has no attribute 'SignalRepeatedHadronization'

Hello, I'm wondering if someone can help me. I'm trying to test a new DecFile with Gauss v49r11 and am getting the following error:

Traceback (most recent call last):

AttributeError: '<class 'Generators.GeneratorsConf.Generation'>' object has no attribute 'SignalRepeatedHadronization'

Other DecFiles seem to have used SignalRepeatedHadronization in the past so I'm not sure what the problem is here. Any help would be much appreciated. Many thanks.
