Ember's subsumed fire blast can't be used with lavos anymore

[Shadowdoul4]

Hello,

since the Jade Shadows update, I can't use Ember's fire blast ability that I had installed on Lavos.

In game, the ability icon appears greyed-out.
And when I try to use it, it doesn't activate and the message "need more energy"  appears (more or less I tried to translate it).

 

Anybody else has the same problem ?

Thank you for your time and have a nice day.

I wish I had lavos to try, did you try it with / without the augment?

Yep, I tried with no mod installed and it didn't work.
