Thanks for the save file!
I've had some trouble actually running Factorio after syncing mods with the save. I was not able to load the save, but I was able to start a new game with the same mods enabled. I was not able to reproduce this issue. From what I could glean, there is another mod (or mods) changing the prototype used to create the hydrogen plate explosion (e.g. making it create water on Nauvis, similar to nukes creating lava on Vulcanus).
Some followup questions:
- Does denatured hydrogen still do damage when it spoils?
- What happens when you use a nuke on Crucible?
- Do you have a hunch as to which mod(s) might be changing to prototype? If I could narrow it down it'd be a lot easier to test.
Thanks!
