Hello there!
I've been having this problem for a while now, before the latest patch came out, this is what it says:
An exception has occured!
ORGE EXCEPTION(5:ItemIdentityException): Cannot locate a resource group called 'Terrains/temp' for recourse 'temptTerrain.material' in ResourceGroupManager::openRecourse at c:\ogre_161_tag\OgreMain\src\OgreResourceGroupManager.cpp(line 685)
- I've looked at the Missing File topic, and I didn't find anything related to the problem. >> Hope you can help!
