I don't know, but it seems the research order is wrong, and the setting is not working, Aneutronic Fusion is only requiring Vanilla Science. Tested in sandbox, heres both saves https://drive.google.com/file/d/13nJS4duHCxjPaEioN36KWHIzdqzn0kAI/view?usp=drivesdk

https://drive.google.com/file/d/1-DpmsOMjJ6KWO-jsOxO3wZze6PiUFA9l/view?usp=drivesdk With both SE settings disabled,
https://drive.google.com/file/d/1LMKeGac4xU6SfvEnwWczQEy4DY2GREH4/view?usp=drivesdk With both SE settings Enabled

Tried with only SE, its requirements, RFP, and RFP:W. Saw same behavior.

Seems like something in 1.8.10 broke everything regarding K2+SE science, taking the new versions off of the mod portal until I fix it...

i'm sorry for probably ruining your day. wish you good luck in fixing. Really have enjoyed the mod for the year+ i have used it.

Took a while to figure out what's happening, apparently the file that changes techs when SE is loaded was silently failing because of the composite aneutronic reactor setting removing the DEC tech.
Manually delete the mod and redownload 1.8.10, it should be fixed now. Should also fix the problem you're having in the other thread.

Will try now thanks!

tried downloading the correct new version, and still having both issues, really strange. Double checked, both server and client has the new .10 both bugs are still happening.

Have to go sleep now, so I'm taking down this version too for the time being. I'll fix it tomorrow, hopefully.

Sleep well!

So apparently I just uploaded the wrong version yesterday... try redownloading the mod, it should actually be fixed now.

Testing now!

Yep confirmed! works thank you so much.
