Blink Arrow issue (kicked to main screen)

Hi,

I regularly get "an unexpected disconnection ocurred" immediately upon using blink arrow. I get kicked to main screen (log in) with no error message other than "an unexpected disconnection ocurred" in bottom left.

It must have happened at least 50 times this league if not up to 100 (and never any leagues before). It's gotten to the point where I'm afraid to even use the skill while delving in fear of a crash and losing progress. I'm fairly sure it's never happened outside of blink arrow use.

I'm playing in lockstep mode on DX11 (auto). I can try switching to predictive and see if that solves anything, but I wouldn't want to play non-lockstep long term.

Specs:
Windows 10 64-bit
Intel Core i5-7300HQ
NVIDIA GeForce GTX 1050 Ti
RAM: 8 GB (1 x 8 GB)

If any more information is required let me know.
