Quite hard? I mean shame on them for letting this bug through in the first place but I'd be pretty horrified if someone at CB tried to hot-fix this problem out

Quite hard? I mean shame on them for letting this bug through in the first place but I'd be pretty horrified if someone at CB tried to hot-fix this problem out. This isn't a small agile organization, it's enormous and may not have any route to get a patch out in less than a week due to QA requirements. (That isn't to say such slow deployment processes are good, but they do exist and may be contractually required)
