Nanopneumatic jackhammer targets wall instead of jilted lover, can't select target

I started up in v2.0.206.51 with a Child of the Deep and I’ve got a nanopneumatic jackhammer, down in the tunnels below Joppa. I’m trying to hit this jilted lover, but I just hit the wall the plant is on. I thought about disabling dig in the ability menu, but it looks like that’s not an option anymore. I think the game is just defaulting to dig when you hit a tile with a wall in it.
