The moderators recently added a new close reason to the Off-Topic list:
This question was caused by a problem that can no longer be reproduced or a simple typographical error. While similar questions may be on-topic here, this one was resolved in a manner unlikely to help future readers.
This was adapted from the new reason on the main Stack Overflow site. The only difference is that we removed the "This can often be avoided by identifying and closely inspecting the shortest program necessary to reproduce the problem before posting." part, as this is either difficult in some cases on the site, or it doesn't make sense. We may decide to add modified version of this back in.
This close reason is an attempt to have a default that aligns with the true intent of the old "too localized" reason that sites used to have. This reason should really only be used for typos, non-problems, and other similar questions that won't help future readers. For example, I closed this one with this reason:
This question ended up being a non-problem, and the module was working as expected.
Please use this new close reason wisely.

This was revised to
This question was caused by a problem that can no longer be reproduced, was solved by a cache clear, or was a simple typographical error. While similar questions may be on-topic here, this one was resolved in a manner unlikely to help future readers.
emphasis mine to show the change.
