Grineer Mobile Defense Stairs Issue

[Meenmu]

I've been running kiste to level some crappy weapons to up my mastery and I have been noticing that many of the stairs in the tile where you defend terminals/pod prevent you from funning up them. If you try to run directly up them, you get stuck on the stairs. The only solution is to jump over them (a pain) or run diagonally (which on narrower stairs means darting left and right rapidly while trying to ascend). Is anyone else having this problem?
