I imported a models library from the other save via the BP export/import feature.
The import was successful. The deployment, however, was not.

Error while running event compaktcircuit::on_gui_click (ID 1)

Thanks for report. Can you give me the blueprint that cause the crash ?. Thanks you.

Library is too big to be posted here directly )

Link to the blueprint book: https://disk.yandex.ru/d/3aF77yXzJAC83w
The mod missing for the 1st one is the Useful Combinators; the processor model is mini-proc "Signal Minimum (true)".
The second was big processor with the model "Signal Minimum Backup" (names may be not 100% correct).

Also it would be useful if the BP export would generate processor icon equal to the processor icon from the model.

Thanks. Should be fixed in 1.1.4
