Trivial Potential Kudzu Bug

[amaranthineApocalypse]

Effect: Kudzu becomes dormant and stops spreading
How to reproduce: Unknown, Potentially random

I planted kudzu today. It grew just fine at first. Hopping over doors and such. But then it got to a point where it stopped growing. There was nothing in the way. I tried to trim it back and see if that would trigger it to grow again, but that didn't help. It didn't even regrow to the places it had already grown over once before. It's like the kudzu went dormant and never woke up. Not sure if this is how it works, if this is a bug, or what

I'm fairly certain this is the intended functionality.
