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"

In order to help troubleshoot this error I'm running on the 4.3.1 code branch with a modified LinkerLoad.cpp file. It was modified to address my previous issue that was resolved a few weeks ago. The code change is documented here:


Here is link to the LinkerLoad.cpp file: http://1drv.ms/1q786AU

Here is a link to the call stack dump from the exception: http://1drv.ms/1q78e3m

Thank you, - jeff

I did what was mentioned I removed and recreated from scratch the CharmState and CharmSave blueprints. I was able to get past the error. We are now stuck on another show stopping crash that was posted a week ago found here:


Was hoping a developer could guide us as we cannot keep removing/recreating files.

Sorry for missing your other post. I have assigned it to myself and have started some preliminary investigations into the issues that you described there.

Hi jeffvoight,

Sorry to hear that you are having an issue. At least for starters we'd like to be able to get you back inside your project, and we can probably do that by having you open to a different default map.

Go to Unreal Project/YOUR_PROJECT/Config

Open up DefaultEngine.ini

You will see a line that says EditorStartupMap= with the path to your persistent.umap

Remove the line, save the file, and try opening your project. Hopefully from here to can try to identify a troublesome asset and pull it out if necessary. One of our support engineers has been asked to look into the issue and will see if they can determine any other information.

I hope this helps.

Hi jeff,

As Stephen mentioned, getting back into your project is not a big problem. I opened the DefaultEngine.ini file in your project and noticed that there were two EditorStartupMap=... lines there. If you delete the line referencing your persistent.umap level, save, and re-open the project, you will be able to get in again.

That was the simple part of the issue. Unfortunately, what I noticed when I was able to get into your project was that trying to open any level other than the default level, or trying to open a Blueprint, would cause the same crash to occur. I did not try every Blueprint or other asset that you have in the project, but every Blueprint that I did check caused a crash.

This does not appear to be related to the changes that you have made to your LinkerLoad.cpp file. I tried opening the project using versions of the Engine both with and without the changes to that file and saw the same crash in both. I am going to see if I can get someone on the development team to take a closer look at the callstack for clues to what is happening.

In the meantime, do you recall what you were last working on in the project before this issue started happening?

I may have spoken too soon. I just discovered that there is one Blueprint that I am able to open: bp_board. After I have opened this Blueprint, I am then able to open all of the other Blueprints, and even load different levels. Until I close the project, which results in the crashes starting again the next time I open it.

I am still going to have a developer look at this, but at least it looks like you will be able to access your Blueprints and levels. I have not tried actually making any changes though, so I do not know what effect, if any, that will have.

I narrowed it down to either the CharmState or CharmSave blueprints. I was able to revert to a previous version of those and it loaded fine. It is one of those blueprints. I just started to implement my saving when this all occurred.
