After a while of not playing SV I decided to update smapi and all of my mods. Afterwards I was getting drops of about 30 frames while on the farm. They would happen randomly, sometimes being set off by harvesting a plant, or opening the menu. I reinstalled the game and smapi without mods and was still getting the issue. Works fine without Smapi. The log doesn't show any errors.

Hi @JohnnyAppleseed12. Please post a message in the SMAPI support thread, with a link to your latest SMAPI log after a frame drop occurs. 🙂
