What's wrong??

[alexanderbez]

Thanks for the issue @ssssssu12, but it's a bit difficult to see if there is any problem w/o a stack trace. Can you please post the stack trace that gave this panic?

I get the same error when simulating a delegation tx:

Ohhh this issue is benign and already fixed in #4135. I'll add that to the wishlist.

[ssssssu12]

@alexanderbez Thanks for your support.
This problem will fix on the release v0.34.2 ?

[alexanderbez]

@ssssssu12 yes :)
