"road to kurast" town portal visual bug

itd be good to know if anyone else has had this happen. i sprung for the preorder and got the fancy “road to kurast” tp, with the stone pilars and green portal. its fun and all, but nearly every time i use it now there is a visual bug where after the pillars rise and the portal opens the pilars drop back down again, often one then the other, while the first comes back up again, or some various combination of this. the portal still works and all, but given the whole point of this cosmetic is to be… well… cosmetic, its super lame that its not working correctly anymore. im pretty sure it worked just find before the expansion dropped (during the preorder time), but now it glitches almost every time i use it. anyone else have this issue? i did some searching and didnt find any mention of it. its been doing this for weeks now at least, ever since i started my expansion seasonal spiritborn run. normally id just swap it out for a different tp, but this run is the whole reason i got it in the first place.
