Game slows to a crawl when opening dyson editor

Not sure why, but when playing the game now since yesterday anytime I try to open the dyson editor, the game is essentially non-functional. Only have about 4000 sails up in the main system. Game runs without a single issue otherwise, no FPS drops or issues when looking at all the sails, and in task manager, the CPU utilization drops to 0% when i go into the editor. If i hit escape enough I eventuall yback out again to completely normal FPS and functiniong. Anyone else have this issue and know of a fix?
