I've been building a large worldspace for about a year now, without very many hiccups. But, for the past couple weeks or so, just about every time I save my work, the Creation Kit LE crashes. On some rare occasions, it lets me save, but the next day when I try to save, it crashes. I now have it auto-save every 15 minutes. I mostly have success with that. But sometimes even auto-saves CTD the next day. Most of the time, I have to go back 2-4 hours worth of auto-saves to find a functioning esp. So, I'm barely making any progress. EDIT: I don't know if it makes a difference, but I noticed today that Creation Kit was using up to 3263 MB in Task Manager. These are the warning messages I've compiled: Assert File: ..\..\ScrapHeap.cpp Line: 656 ScrapHeapManager::AllocateBuffer() - Could not reserve memory for new scrap heap buffer Assert File: ..\..\ScrapHeap.cpp Line: 347 Failed to commit initial memory!
