[OPEN] [ECO] Disappearing Grubs

I also have this problem. I use grubs because I'm not fond of all those bug legs. But they keep disappearing. Sometimes they last 4-5 days, but just now, they disappeared only a brief moment after I purchased them. Grr, you know?

I have all available packs and kits installed and my game is repaired and up-to-date. It happens both with and without mods. My Sim is living in Port Promise, Evergreen Harbor. The neighborhood that shipped with Eco Lifestyle.
