don't know if it's specific to this update or maybe even it's just me, but i can't see daylight anymore... i can see the sun but the sky stays dark:(
following your suggestion i tried /unlock, unfortunately this was a command for another mod i have installed that did something i really didn't want...

i have tried setting the sun to 10 (on the server and the client)...
also where is the "lock button" alluded to un the config file as being toplight or bottom left if i recall correctly? :/

No..
not unlock, but /locksky false.
And the config is on the client configuration.
Try that and reopen this again if it does not work.

ahhh yes! thank you, now i have daylight again, i also have an issue with "/time set day" causing a server crash/hang though...

Make it as separate issue.
