A Turtle won't eat seagrass

Put the summary of the bug you're having here

What I expected to happen was...:
I clicked on two turtles with a stack of seagrass and hearts should have appeared over their heads

What actually happened was...:
only one of turtles had the heart particles. the other didn't even eat it. Then It swam all the way back to its island and laid eggs so yeah this is just me being stupid.

Steps to Reproduce:
