TASK DESCRIPTION

When using board.topics(reverse=True), after the first batch has been iterated (default is 100 topics), the generator fails with KeyError.

from pywikibot.flow import Board
site = pywikibot.Site('mediawiki', 'mediawiki')
board = Board(site, 'Project talk:Sandbox/Flow test')
topics_list = board.topics(reverse=True)
for topic in topics_list:
    print(topic)

results in

[[mediawiki:Topic:Sojpiv245cuiw67c]]
[[mediawiki:Topic:Sofvr5snmpjxk7po]]
[[mediawiki:Topic:Sofvkmr22vxpo1x4]]
[[mediawiki:Topic:Socee2qdhcihhfaf]]
