I removed mekanism that might had some quests associated with it. It crashed on a world gen.
Any way to not crash the world but also not render the used mods items?

I re added the mods, but still getting a crash:
Do you know why would it be?

Well for starters you're using a BQ2.x.x expansion with BQ1.x.x which is incompatible

"BQ1 (1.x.x) expansions are NOT compatible with BQ2 (2.x.x) releases! Always check your versions before updating" - Notes in Better Questing project. And since it doesn't seem to be a real issue you should close the thread.

My worlds doesn't load far than the loading world screen. Is it might be caused by this?
better questing 2.3.179
standard expansion 2.3.144

The problem is that you released a 1.x.x update as the "latest" 1.10.2 file and the curse launcher will see that as a needed update. Modpack authors update and crashes galore.

I have marked the versions separately as Release and Beta but Curse is still sending them both out as recommended updates... >_>
