Indago waveform is not showing after Design reload

Hi,

I am facing the issue where indago waveform goes blank after I reload design. Below are the steps 

1. I simulate and open the waveform in indago

2. find the RTL issue, fix it and re-run

3. reload the design after test is done.

After step 3, 70% time it is okay but 30% time it does not reload correctly and all the waveform window is blank. (though signal name is still visible)

If I close indago, (remove myDb and rerun the test it works fine.

What could be the issue?
