Stormcaller locks up + cannot cast crow form

During the game, Stormcaller glitched out massively. Crow transform refused to go and was greyed out. Along with this, he refused to do any other action until the one he was currently doing was completed. Say you told him to move to point X, you could not cancel that action until he arrived at point X. You could not swap, and if you told him to attack something, he would refuse to do anything else until the enemy or he died. The other persona (Grove Guardian) did not have any problems. Regrouping, dying, persona swapping did not enable crow form again.

Crow form is greyed out. It remained this way for the remainder of the game (About 5 minutes)

this is a glitch with changing forms inherent in wc3.

the same happens with avatar, almost 100% of the time.

this hero will probably need a remake if this becomes a serious issue

That kind of forcing you to wait happens in other games sometimes, it's a feature of warcraft, has something to do with the 'insert' button on your keyboard, but it shouldn't make your crow form black out, so maybe that's different.

Did little flags appear when you told him to move?

No flags appeared, nor did pings on the map show up (which would be waypoint mode)

Stormcaller is being removed in b3 in any case.
