@Fatyx:

[Mystcraft] Someone is trying to get the age name from an improperly constructed world provider with dim id 5

That seems to be the problem. Are you trying to enter a Mystcraft age? You should delete it if the Mystcraft world is not important. To do this you should go to your /saves/ folder, search for your /world name/ folder, enter it, and then look for DIM-5 folder.
However, you should get Nitrado help support, if you can't do this yourself. Tell them you have a corrupted save and ask them nicely to help you.

That error occured again, so i guess it's any age i log out in?
I had an age with:
-ocean biome
-single biome
-No weather
-normal sun
-normal lighting
-normal moon
-red
-sky colour
-void
-ender starfield
-clear modifiers

and i build a 100x100 floor with a few solar panels, a nuklear reactor and a me-network with some IC² mashines.

I've been getting this same error on a different server. I logged out in the overworld. Is it possible that set waypoints in ages are somehow linked to this? I'd like to find where the data for waypoints is saved in ftb, so I can remove all my waypoints in ages and test connecting to the server. I have not had any luck finding the data so far.
