When we move the project, we copy the entire project suite and folder onto separate machines. We use SVN/GIT to source control the project. I believe this is not the issue.
The table file size is usually <= 30kb of data and a 15x15 grid style sheet with string values.
Test Complete version 15.30.3.7 (we already tried rolling back a few versions as this is a new issue we discovered).
After we restart TestComplete and check the tables some are corrupted. If we attempt to run TC again TC crashes and says "TestComplete has encountered a problem in module tcRTL.bpl and needs to close. We are sorry for the inconvenience."
When I say the table is corrupted, imagine you had a 15x15 excel sheet filled with data then restarted test complete now that 15x15 sheet is 0x0 or 10x3 or 3x10 or YxY. The data is missing or partial.
