Possible bug: Twice today I've cancelled my ult by activating another ability.

Like the title says, twice today I've thrown my ult, with Mei and Tracer respectively, and then hit recall/iceblock and have my ult suddenly disappear. It isn't spent so the ult isn't gone as such, it's just as if I never threw it, but I DID hear the ult line go off and see the ult actually get thrown out. It is really annoying because the cooldown and moment to fire it are both definitely gone.

Basically: Throw ult -> Hear ult line/see ult animation -> Iceblock/recall -> Ult vanishes, still charged -> Rage
