real allocation work not saved

Hello,

I'm testing via Chrome the Projeqtor 5.3.3 version.
I have entered 1 project fixed price with about 150 activities. I have assigned 5 resources to each activity. The same resources. There was no planned duration of assigned activities. While entering the data, users couldn't save any real work allocation - after entering and using the save button there was an icon "processing" without the communicate "real work allocation saved" at the end. After changing the week and coming back, there were no data.
As far as I understood, the process was too long to finish because of plenty of affectations dedicated to the same resources. When I diminished the amount of affectations for the resource, this one could save the real work allocation.
The point is, there was no communicate after the attempt of saving informing, what is the problem.

Best regards,
