After today's update, I get this error:

Failed to load mods: Error in assignID: item with name 'yeet-ske_heb_248' does not exist.

Source: ske_rubia_tech (technology).

It's asking to disable the Shattered Planet mod. If I do so, it leads to another error, asking to disable the All Planets mod.
Can't load my save anymore.

Thanks in advance ;)

I tried to roll back Rubia to version 0.69.92 - (about 12 days ago). Didn't work, got stuck in the loading screen.
So, for a temporary fix, I've removed skewer_shattered_planet from the info.json.

Appears to be a problem between Shattered Planet, Muluna, and Rubia, according to this thread, issue may or may not be resolved in the latest Shattered Planet update? Or they're working on it.

Removed Shattered Planet mod as of v1.0.21, due to other potential conflicts in addition to the WIP issues

Thanks, but now it seems to have a new problem

rubia 0.69.102

The downgrade to 0.69.92 doesn't work either now

Update 0.69.103 was just released, and it fixed the mod-loading issue. But causes this when I try to load my save '^^
Looks like Rubia's dev is working on it.

The mod Machine Upgrades (0.69.12) caused a non-recoverable error.
Please report this error to the mod author.
