I'm seeing worms pop up briefly in the railroad cave. Not when I dig... just sporadically. They appear, wiggle around, and then suck back down into the ground... I've tried catching them and they disappear, causing my character to stay in position with the net down for about 5-10 seconds before being able to move again, but not catching a worm. I've tried digging in the same location to no avail... wondering if this is just a glitch or if there's some secret way to get em?
