[GAMEPLAY] Teemo and Homeguard don't mesh well.

So I've noticed this before, thought I just did something wrong, but the other day I was playing Teemo, and I had homeguard on and when I backed, to get back to base the homeguard movespeed wasn't applied. I sat around on the base for a good couple of second to make sure it wasn't just me still being 'in combat' but it was not. I also tried leaving the base and walking back to it to have it apply, and it wouldn't. It was random, because in some situations it will indeed apply and all will be well, but in some random situations (maybe not random, and I just haven't found the link yet), It wouldn't apply itself to me. I started to think it was because of my shrooms, perhaps they put me in combat, but I only experienced the issue one more time and there was no one on any of my shrooms at that time, so I can't be sure as to the cause. Is this a known issue? Am I just crazy? Both?!
