Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Crash on load after adding function to interface

I'm having an issue with a blueprint interface. Specifically, whenever I add a new function, and add an input argument to it, the editor crashes when I relaunch it. The input type doesn't matter. It crashes if it's a bool, text, or struct. I can add functions with arguments to other interfaces, and it doesn't create any problems that I can see. Additionally, once I add the function and before I relaunch, I intermittently see soft crashes, in which the CrashReportClient.exe is invoked, but doesn't take down the editor.

The crash is pretty generic, and appears to be a general crash that occurs when the crash reporter doesn't launch correctly (based on searching the error in question).

alt text

There are already a dozen of so functions in the interface in question that use input arguments.

I'm getting the same crash on multiple computers, so some of the proposed solutions I've seen (it's a windows install issue) seem unlikely culprits.

The log file doesn't seem to be giving up much in terms of clues either:
