Does only happen on the client instance, not on the server.

the reason you couldn't find a duplicate here is that this was reported on discord so there was indeed no github issue for this yet

I want to say that this is a duplicate (as I've seen that crash before), however I can't find it. This was fixed in e808136, and will be fixed publicly whenever 7.99.5 is released.

Thanks, was trying to find a duplicate but could not find one. If its already fixed in dev I will try to bake my own version of bc for the moment :)

Tested my self made jar and confirm that it is fixed in dev

Fixed in 7.99.5
