Hi,

I'm playing ATM6 and after updating to the latest Version of Bigger Reactors(biggerreactors-1.16.4-0.4.3.jar) I get the error Message down below.

crash-2021-03-19_12.24.54-fml.txt

It worked fine with the previous Version.

This is an issue with the curseforge launcher, you have incompatible versions being used.

was noted on curseforge that this doesnt describe the problem, because it doesnt, soo

the curseforge launcher keeps multiple mod versions when updating and/or rolling back, in this case its attempting to load Phosphophyllite-0.5.0-alpha.1 with BiggerReactors-0.4.3, which are not compatible with eachother.

if you are having this problem, you are probably playing ATM6 or SLOP2, you will have duplicate Phosphophyllite jars in your mods folder, keep only Phosphophyllite-1.16.4-0.4.5
