@endumls

Unsure if this is upstream or not , but I do occasionally encounter situations when a failure like this occurs selectively

[naddison36]

I've retested 0xa76223b08efc5c293437b8f5673ed2b2757ba7f9c405dab5c98620c463ed9b57 against TurboGeth using the latest version of tx2uml and it's now working.

Pls let me know if it doesn't work for you or you find other examples
