Dying (and maybe getting knocked down) during ability casts prevents using abilities after respawning

[Rubat]

Basically the annoying issue when sometimes you just cannot use any of your abilities or switch into the operator.

As far as I can tell, the cause for this is dying during casting or starting to cast an ability.

As an example - harrows 4th ability. It gives you invulnerability, BUT if you die after pressing 4 and before the invulnerability starts, and then you get revived you can no longer use any abilities. It will say "ABILITY IN USE". This has happened to me a few times when fighting the ORBs.

 

The only workaround for this as far as I can tell is jumping into water or maybe dying.
