Losing data - multiple users?

Hi MapHub Community!

First of all, I´m really greatful that a community and a tool like this exists. It´s so useful for the visual people like myself and for a project like the one I´m working on, where people are located in different parts of the country.

I want to comment that I have been having some issues with my map. Basically we are building it with a team of 5 people and we are all using the same user. I can confirm the data has been saved by one of my colleagues, as I can see it when I login from my computer. However, the next day the data has disappeared and all the work has been lost. I wonder if there is a limit of items you can add? Or if it has to do with the number of users logged in at the same time?

Yesterday for example, one of my colleagues added 2 items and after 2 hours they had disappeared.

If you can shed some light on this issue, I would really appreciate it, as I´m really looking forward to present this map ready next week to my team.

Thank you!
