Issue with Numinia installed causing errors with other mods. TFar's Dank Storage has an issue with casting air to a Dank which we suspect is Numinia as removing it solves the issue.

I've also seen errors like this which reference Numinia explicitly at the start. (This seems to be to do with handleBreakSpeed which I guess is to do with mining speed while the first lot is handleBreakSpeed and icon changing. (I assume when stuff in the hotbar is dropped.))

That's not on my end as that was fixed on this end months ago:

also, your log regarding the breakspeed casting is using an obsolete version
