Hi Casey
To Add to Rui's comments
The Geodatabase API used by TBC, supports only simple feature classes/ geodatabases.
This means advanced functionality like geometric networks, attachments, relationship classes, sub types, Editor tracking etc are not supported and can potentially cause problems like this, when writing back to the *.gdb
As a result we recommend customers only use simplified geodatabases when working with TBC.
Many customers use a 'staging' geodatabase to get round this problem
i.e. make a copy of the original geodatabase without any of the advanced features to be used with TBC. Once the updates have been committed from TBC back to this *.gdb you can use the various ESRI GP tools to load this data back into the original geodatabase with 'advanced' configuration.
