Editor will not save map
After this last update, I can no, longer save my maps in editor. We went to play one of my maps last night, everything was messed up, no lighting colors. Map worked great before update. So, I thought it was the last update that is problem. I opened editor, loaded my map and tried to save it, hoping it would fix any issues with new or old assets. It starts to save, the it pops up saying Could not save file. Check log for details. Where do I find the log so I can see what the problem is.
