I'm running v1.7.5 on Windows and have just started to receive the attached error.
The only change I made to the task in question was I changed the due date. I haven't changed contexts for the task. And I haven't changed any of the contexts at all so I don't understand why it thinks it should be merging contexts.
When I looked at my task list this morning it had also managed to duplicate this task so I now have ~99 instances of the same task. I've manually cleaned up the duplicates and modified the subject/notes on the remaining task, but it still won't sync.
Help please? Are there any log files I should be looking at to get more information?
