daewoosh, thank you, I saw your previous answer but I don't understand what do you means.

Telegram update is a JSON and the string representation of 'kicked' or 'member' status does not depend of the int type.

I'm use NodeJS on the backend so values bigger that 2^32 are handled correctly.

I made logs to check if the user ids are correct or not, and they are ok.

Probably I don't understand something =)
