When I have the latest version of both MrCrayfish's Vehicle mod and Regeneration installed, you can't craft the vehicles, and you also can't make fuel either

Do you have a latest.log at all?
Does it work without Regeneration?

It does work without regeneration. where would i find latest.log? also i've been having issues with the Bio Container and the unknown ore @Swirtzly

Sorry for the slow reply, you will find a log in .minecraft/logs
But, you will need to re-produce the issue and then close the game as soon as it happens

latest.log
let me know if that works. can send again if needed

Sorry for the late reply, but I cannot find anything wrong and nor can I re-produce this issue. I am going to close it for now, please comment if you find anymore information on it.
