When i start Tekkit main i get this error:

I have i nether set up a pump to pump out lava and send it to waterproof teleport pipe that is set to no-recieve liquids and frequency 1, at th home in the overworld i have set up 2 geothermal generators and a waterproof teleport pipe with recieve liquids and frequency 1. The lava is not comming to the overworld, even if i have dimensional anchor. P.S: i play on multiplayer with my brother.

When i go to tekkit singleplayer i can't see my world. I go to %appdata%/techniclaucher/modpack.../saves/ and there is my world but ther world isn't showing in game. And there is missing 2 files: level and level_old, its just disappear. The world is working fine but now... I didn't touch anything.
