Grass never stops growing

[aurelien.fontaine78]

Hi, i have this issue where the grass never stops growing even if i have built right next or even upon the stem. My base is basically a forest at this point. 
It does have a little charm but it feels very glitchy and unpractical, does anyone have the same issue ?

I do as well. Only have a small starter base(dont really plan on going big until more options are available) but I have 2 grass blades that grow right through the foundation. I did originally cut them down all the way before building there.
