Abrams ult will get stuck in between "seems" in map geometry.

[victorvdb]

If you hit a wall so that you slide downwards against the wall and then you hit a "seem" with Abrams ult you will get stuck in it.

See attached file for an example.

This has been the case since Abrams release, no idea why this hasn't been fixed yet or bandaid patched by allowing Abrams to manually cancel ult after descent or give him some movement while falling so he can unstick himself.
