Thanks spuggiehawk, I am glad it is working. I posted over on the FTB forums too and there is a guy who made a Hex fix to set the start and end dates from [month 10 day 29 to month 11 day 01] to [month 13 day 00 to month 13 day 01], which will never exist. My mod changed the variable that would be set to true in that time period back to false on init. Doing more reading I discovered there are two time periods. The crash also happens between [month 04 day 00 to month 04 day 04] so I have updated my mod set the second variable that is set to true during this time period back to false on init. Same URL.
