had some issues with images not being found cause of capitalisation
-Plutonium-239.png / plutonium-239.png
-Used-up-MOX-fuel-cell.png / used-up-MOX-fuel-cell.png
went ahead and changed on my own (changed it everywhere to start lower case including the files calling the images)

Also had some issues with the technologies (might be due to using this mod with other nuclear mods but unsure)
-plutonium-processing-1 & plutonium-processing-2
renamed them to plutonium-processing-one & plutonium-processing-two (same here in all files using these)
seems like if you use numbers at the end its considered infinity technologies?? not sure.
Edit: might has been an issue with the mod "Plutonium Energy" - their technology is called "plutonium-processing". - would need to test that.

tbh, i think this mod deserves an own GitHub repository, so we can du pull-requests on potential bugs

is it preventing startup? sorry for the late response. it seems to be working on my end but i see the issue and will fix it next time i update it. i have this mod on github. (unless im using it wrong)

both prevented startup.

when i click on the GitHub-link i get an 404 Error.

ok. is the new version playable? on my end it's running fine, but there seem to be some issues most people experience that i am not getting

When you are testing your mod on your PC, make sure you test it only whith the .zip file

and please try to post your code in an GitHub-Repository, there i can help you more than just reporting the error-messages

ok, i think i have the sprite name issue fixed. i set betternuclear as a project in github. i hope it works. it works on my end.

i am creating mods myself, and i can say that an Repository is way better than a Project
