Not sure if I need to post this again as if other people already posted other examples, but still.
Bot McGinnis got stuck in the same place until moved after getting melee hit by Abrams.
Easy to reproduce, just jump on one of the two railings in the base that has a catwalk under it when sitting behind the catwalk itself
Most times the character will unstuck themselves but it is also quite easy to just get stuck there
In this screenshot my character was just spazzing out
You can get "stuck" under the catwalk while trying to grab the zipline.
While it's just as simple as pressing jump to get unstuck. I figured thought it'd be worth noting.
