not only different clients on different operating systems. Last season change I logged in and saw it had changed to spring so I told in guild chat. Guildie said he still saw winter so ported to reset it and it didn't. He wasn't intrested in digging so didn't restart client but for over 2h it stayed winter on his client while he was hunting and porting until he crached and had to restart the client. We where both using windows clients and I can see that as a big dissadvantage if you are unlucky and logged in with your friends just before season change you could be playing thinking it's still the old season till somebody craches. (we all know how much ryzom craches for some more then others in my case about once every 2h but we should not have to wait on a crach to see season has changed)
