I got an error while trying to do an optimization for one out of 14 regions. My steps are:

1) In the "regions" I put my region as a reference for indicators and turn off calculations for all the other regions

2. Then I assign NEMO (Cbc) to be a solver in optimization

3. The optimization does not run, but if I put additionally same solver for the first region in the raw, NEMO starts, but the following error appears:

NEMO encountered an error with the following message: SQLite.SQLiteException("database disk image is malformed").

To report this issue to the NEMO team, please submit an error report at https://leap.sei.org/support/. Please include in the report a list of steps to reproduce the error and the error message.

nothing

Also, sometimes there is a message "Verified that transmission modeling is not enabled", does it mean that modeling of transmission system is possible?
