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 better assist you, I'm going to need for you to provide me the logs from your mobile devices.


  • Attach your phone to the computer

  • Go here: C:\NVPACK\android-sdk-windows\tools

  • Open up Monitor.bat

  • Launch the program and save the logs

If you cannot get Monitor.bat to open, please go to: - C:\NVPACK\android-sdk-windows\tools\lib\monitor-x86 - Open up Monitor.exe - Follow the instructions above

iOS Windows:

  • Open iPhonePackager (Engine/Binaries/DotNET/IOS)

  • Select a uproject file (Optional)

  • Select the Advance Tools tab

  • Select Other Deployment Tools…

  • Select Backup Documents…

  • Select the IPA for the game you wish to get a log for

  • The documents directory data will then be copied to Engine/Binaries/DotNET/IOS/IOS_Backups or GameDir/IOS_Backups if a uproject was selected

  • The log can then be found at IOS_Backups/Game/Saved/Logs

iOS Mac:

  • Open Xcode (Install Xcode if you have not already)

  • Open Window|Devices

  • Select the device you want to get the log off of

  • Select the app you want to get the log from

  • Select the gear icon under the app list

  • Select Download Container

  • Select a location for the container file

  • Navigate to the file via Finder

  • Right click and select Show Package Contents

  • Navigate to the location of the log (AppData/Documents/Game/Saved/Logs/)

Make sure that you highlight all of the logs, because they do not save unless they're highlighted.

Thank you!
