I've been using the Sweeper that spawns behind the window in the Meteorology Sim Lab in the Terra Dome to farm lim, it was spawning reliably every time I exited and loaded in, but I messed up one time and accidentally let it get away. Now every time I come back it just isn't spawning anymore when I look through the window. I've tried leaving the area and coming back and restarting the game. There was an autosave since it happened, is there any way to get it to come back or am I just out of luck now?
