To help me track down issues you are having please follow the following steps:

The mod

1. Find the mod config file for your world, at %AppData%\\SpaceEngineers\Saves\<WorldName>\Storage\1958161003.sbm_GridSpawnSystem\Settings.xml
   
2. Edit the file and change the LogLevel setting to TRACE
   
3. If possible make a workshop version of your world setup to share
   
4. Reload the game and reproduce your crash
   
5. Copy the log file from %AppData%\\SpaceEngineers\SpaceEngineers.log
   
6. Upload the log file somewhere it can be shared, such as dropbox

Then please create a post under the BUG REPORTS topic, with links to:

• a description of how to triggered the crash
  
• link to the log file
  
• link to the workshop world
  
• link to the blueprint you were trying to spawn on the workshop

This will give me the best chance of being able to reproduce and fix your issue. thanks!
