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"

APC_INDEX_MISTMATCH Crash when opening project file

I am currently working on a group project and experiencing a crash when trying to open our project file. I had a graphics card problem and had to reinstall windows, now when I try to open the file it blue screens with error APC_INDEX_MISMATCH.

We tried loading a version with the content removed and this worked fine, all over files I've tested work fine. I am running the file off one drive, however other files on one drive have worked fine.

Trying to run the same file of USB instead of one drive didn't work either.

Not had any problems blue screening with other games or software, just this specific unreal project. We did have true sky installed at one point, however its now removed, not sure if leftover files from that could be causing any issues.

Graphics drivers are all up to date, windows updates are current, unreal is running 4.19.1

Any help would be appreciated, thanks :)
