How exactly do you execute the log import command with which parameters? Do the requests have a userId?

@Kornexl Could you please try this patch https://github.com/matomo-org/matomo/pull/15258/files
and let us know if this maybe helps with counting visits correctly (for new visits after applying the patch)?

@mattab experiencing a similar bug and the patch posted above did not fix it.

The logs do have userids and these are transmitted in the uid-Parameter by piwik/misc/log-analytics/import_logs.py
Prior to 3.13 different userids are counted as the visits
Now the visits don't use the userids but count otherwise.
Nearly every used logline is counted as a visit even when the same userid (same IP, same user agent) clicked on another link one minute later.
The different userids are shown as users in the widgets
That's a breaking change in the semantics of visits

by importing logs there is no cookie set

@Kornexl can you please share a short extract from the log with multiple lines for the same user ID resulting in multiple visits? if you can't share here publicly, feel free to send us by email at hello at matomo.org - please also include the URL to this issue #15242 - we'll investigate further

should this problem be solved with the new release 3.13.1?
I have installed this release today and can check tomorrow after the import of the daily log

This problem is resolved with 3.13.1

Thanks for confirming @Kornexl 👍
