No data in March logged (no replies)

Hi,

I have no data in my PIWIK installation logged from March 24 to April 6 - I think that I updated to 2.12.0 on March 23 and to 2.12.1 on April 6.

But I didn't find any ticket in the change log that could fix such an issue - is this a known problem? Is there any way to get these data back (e.g. is logged, but not processed...)?

Best regards!
