[ARCHIVED] Wild prairie grass in Chestnut Ridge growing out of control

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.99.305.1020
What expansions, game packs, and stuff packs do you have installed? All
Steps: How can we find the bug ourselves? Play for weeks in Chestnut Ridge, I have tested this bug mainly in Galloping Gulch, where the patches of wild prairie grass that grow outside of lots, like near the unknowned horse grave or at the intersection, or near the fishing spots.
What happens when the bug occurs? Those patches of prairie grass will grow over time and when trying to harvest them, it will work, but they will not revert to the initial (first) stage of growth. It is forever fully grown. I abused it and ask my sims to harvest all prairie grass and would do it over and over again on the same patch of grass, gaining lots of grass and collectibles. Thats a cool bug for cheaters, but I also noticed it lagged severely when I approach the zone where those prairie grass grow...
What do you expect to see? Prairie grass growing like normaly on our home lots and once harvest, it revert to the initial stage and do not make excessive lags.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
