Well, I know for me it had been Secretas and Frozeta.
And...I got this when I was trying to boot the save after it didn't crash from adding that mod
The mod More Infinite Research (5.0.21010) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event more-infinite-research::on_configuration_changed
MIR cannot safely add or remove Secretas on an existing MIR save; restore the previous mod selection and original save

Then I got this with Ferrum
