Can't save my city in City Planner with Opera

lhoq

Hello,
after a few manipulations of my city in City Planner, I click on “Save” but I don’t get the confirmation message. My city is not saved.
I do exactly the same manipulations with FireFox and I get the confirmation message and my city is saved.
I use 2 browsers on my PC (FireFox and Opera)
FireFox is in strict mode –> cookies and data are deleted when FF closes
Opera is used only for FoE –> cookies and data are not deleted when Opera closes
I believed (wrongly) that, under Opera, my city was not saved because I still have buildings in the left side –> my former post
Regards

If you have been working on a city for a long time, it can happen that the session is lost in the background.

I have just integrated a “heartbeat” (AjaxCall every 30s) to maintain the session and an auto-save every 20s after the first save.
This way, no city should get lost anymore.
