Although we already travelled to the nether, the quest book doesnt let us claim the reward for the visit (it says 100%); same for the mining dimension, wwere we already have a builder, but it says its 0%, but its highlighted in blue. Same happens with the twilight forest, were the quest says 0% and is highlighted gray.

Help would be very much appreciated!

Known issue, will be fixed in the next pack update

Now Fixed in 0.4.17
