Not A Bug Zoroark Tera illusion type change

[Hunter_Sash]

What type of bug are you reporting? Mechanics

What is the bug?
When Zoroark switches in on an already terrastalized mon, there's a delay in the terrastalized type appearing on it, could be due to sticky web or otherwise.

Are you able to replicate it?

When a type change appears right before the players get control, that's because it's a true type that's exclusively visible in the Check Target menu from gen 7 onward. This is intended.

When Zoroark is disguized as a Terastallized mon, the Tera effect/symbol will not appear, but the type shown in the Check Target menu will be the illusion's Tera Type. So PS is handling this properly. Proof:

(This is old footage so this may have been patched; if anyone has proof that it's different now please report it!)
