Unit responses trigger fps drops

[Hamanito]

Hello everybody,

I play with 1.30.4 version.

I have FPS drops when selecting/giving orders to units that use a voiceline they haven't before in the game.
It seems to me like the game struggle to load the responses.

Disabling unit responses resolves the issue completely.

Apparently some people had this issue in SC2 but I couldn't find a solution online :/

Did anyone had the same issue or maybe has an idea as to why this occurs ?

Btw it didn't happen in 1.27a and I have Windows 10
