I've made a lava generator to power the task screen, but upon connecting it by transfer pipes, the game crashed.
Now, the game crashes each time I open the save file.
Here's the crash report: https://mclo.gs/xUokynC
It also says that the potential causes are with FTB Quests and Forge.

Looks like a weird quirk inside FTB Quests, no idea if I'll be able to fix it. I may switch the questbook for the LTS version of the pack.
