Warning : removing Yii:app()->session->regenerateID(true); https://github.com/LimeSurvey/LimeSurvey/blob/7102654987cf7ca88893f04b7686dd8324441ffd/application/helpers/frontend_helper.php#L1381 seems to fix the issue,
But it worst : since you can loss data (the page 1 of survey is empty with this solution)

I think we need more control on Expression manager : maybe there are other potential data loss with long time server.
Compare a static variable to the current sid in expression before save ?

I have stumbled with this problem but when using the same survey on multiple tabs.
I just feel there should be a checker telling you to not use multple tabs.
