sometimes get wrong offsets

[WangQiqing]

I used the ptyhon wrapper with the API from the Open IE 5.1.0 server, it works well on most sentences, but except for this one that gets wrong or empty offsets for the extracted args. I don't know whether the exception is caused by sentence structure or other problems.

>>> from pyopenie import OpenIE5
>>> extractor = OpenIE5('http://localhost:8000')
>>> extractions = extractor.extract("The fire burned 3400 hectares and caused millions of dollars of damage, killed livestock and burned out property.")
>>> extractions

[GillesJ]

Same issue here, it happens seemingly on sentences with coordinations.
