So my reactions including solids went wrong, while reactions without solids was normal. image
What went wrong?

Please attach the files (you can save all relevant files and create a zip files from the GUI) so someone can try to reproduce and provide better help.

I see two potential issues:

  1. The alias listed in the error message ‘CGR_REF_’ is truncated after the second underscore. Maybe there is an issue with parsing the species name. Please try a different species name see (without underscore) if this helps.
  2. The total molecular weight is not completely balanced (56.0205 vs 56.0208).

You should also look at other warning messages and the .LOG file to see if there is any useful information that can help troubleshooting.

OK. Thank you very much!
