[ARAM(?)] - Zyra plants bug

I got Zyra in ARAM and at first I noticed that, even tho my plants were in range of something to attack, they didn't attack it. Be it a minion or enemy champion. However somewhere later in a calmer moment, I noticed that the target indicators of my plants were on a poro. And unless I attacked something in range of the plants or something attacked the plant(even then it was iffy if they would), they didn't move to attack anything else close by, which did result that in some cases my plants were completely useless. After that game I went into a custom game to see if I was correct, and I was. The plants targeted poros and sometimes even prioritized them over minions nearby. There could also be a thing where they target untargetable objects, which I haven't fully tested. I did notice that my plants also refused to target minions even if there weren't any poros nearby, but Orianna's ball was nearby.
