This happened upon opening a new world, Here's a screencap of my mods folder; the selected files are ones i recently added (and created a new world with them included).

The error is most likely related to one of them i think, but it could've been one of the other mods

distant horizons is correct in claiming it is incompatible. older bliss versions (specifically bliss v2.0.4 and older) do not have support for it.

you need the in-development version of bliss. make sure to read the description/README of bliss's github page. it tells you how to get the in-development version.
