Calvin run length is 500 instead of 360 in the dataset

[Joeclinton1]

I unzipped the Calvin dataset, iterated through the dataset and was surprised to find that many of the 'obs' sequences were of length 500. This is strange because Calvin has a max episode length of 360, so what is this extra data doing there? Shouldn't the agent have been cut off?

I also don't get what information the 'dones' add, if they're always length 500 and all 0.
