This ticket has a single commit that has been in Mantid since v2.0. Did this resolve the issue? (In the absence of a description it's hard to tell.) Is it appropriate to close the ticket now?

This ticket was waiting for some updates in Nexus and eventually was forgotten about. The issue hasn't resolved itself as far as I can tell. If I try to load file WISH18904.nxs I get 0 events. A smaller file 19279 loads OK.

  • type changed from enhancement to defect

It would be good to have a look at exactly why this file isn't loading and to add that to the description. In principle, this seems like quite a serious bug although I guess the users would have made a lot of noise about it if they were seeing it. I also wonder if it's specific to ISIS files because I would have expected the larger SNS instruments to encounter it if it were a general problem.
