Night/Day sequence stopping at 90*

Hi everyone,
I followed this Tutorial on how to do a day/night cycle

https://wiki.unrealengine.com/Tutorial:_Time_of_Day

but im having problems with it. Im using as speed 3.00 and I notice that the sun stops moving when it hits a 90 (either 90 or -90). I have no idea how to fix it or why it is happening.

Thanks in advanced for any help!

10 seems to be the slowest speed possible before triggering this stop at 90… what can I do if i need it slower? I tried using the matinee (which i dont know how to use) but it wont let me add the sun on the list… :confused:
