There's a new update ver.5.3.1 just up today. For me, I usually held on as long as possible for updating. In some cases, new event won't pop up on the older version. Once, there was one occasion while everyone was playing FM, I could still play normally with the older version without fear I'd get sorted in said event. Besides, playing on the older version might protect you from some kind of mishap the new update would bring.I have a problem with mod of version 5.3.0 they asked me version 5.3.1.
