Glitch in the Catch ‘Em event

Hi, not sure if it was already brought up but there is this purple stuff that appears on the base area and at the top of the top lane. They are like thick purple lines covering the spot where wild Aipom appears and the base area’s healing circle is also purple. It’s like the normal look isn’t there but it all still functions. There are other spots that get covered on this map but not in the center etc. Just wanted to let people know
