Combat freeze after selecting Garet's Djinn option

While battling Briggs and its party, the whole game froze. Logs show this error:

I chose a Djinn from Isaac, then tried to choose a Djinn action for Garet.

I'll be taking a look at it. Many thanks for finding it!

I wasn't able to reproduce it.
That's a weird issue, how were you able to make Garet become a Squire?
The error msg you pointed seems to be class related.
What's the djinn configuration you used?
Did you make any changes in class_db.json?
If you can give a more specific step-by-step to reproduce the issue, it's going to help a lot.

Many thanks!

I have tried reproducing it as well in the demo, but I wasn't able either. As far as I know, I got the Mars Djinn that appears on town, grabbed a couple chests then fought Briggs.

What's the djinn configuration you used?

Only Djinn swap was between Isaac and Garet (Flint <-> Fever).
I cannot remember the exact things I did during combat, but I revived Garet on the previous turn with Quartz.

Did you make any changes in class_db.json?

Playing directly on the browser demo.

That's a weird issue, how were you able to make Garet become a Squire?

I think the engine might be holding some reference to Isaac or something, as it is not possible that Garet becomes a Squire.

That's a good point, will check something in this sense.

Thanks
