this seems to also extend to the hammers added by astromine as well, it happens in both singleplayer and multiplayer and the server reckons its a class cast exception

Any new information about release fix?
new crashlog: https://pastebin.com/RE3Rea7N

Here: crash-log

Crash appears after hitting a stone with any hammer.

Edit

Next: crash-log

Crash appears after hitting a coal ore with vibranium hammer.

Edit

Last: crash-log

Crash appears in the same situation as above, but i run MC without Sodium & Indium.

Fixed - just change the "magna" config file; "enableAllBlockBreakingAnimation" to false.

Yup it's a sodium thing otherwise from what I can tell

yeah so this happens without sodium as well so I will change the config file

I am having this issue too. Here's my crash report, hope it helps.

can you provide your full game log through a service such as pastebon?

I just tried readding it to my pack and got some really weird visual errors, I have a feeling this my have been what was happening to start with and Im thinking perhaps this is a sodium bug? will try and get you a log of the Astromine hammers which appear to use the exact same code

crash-2021-04-09_16.59.31-client.txt
crash-2021-04-09_16.59.59-client.txt

these errors appear to be different then previous versions, but again It appears to be some kind of visual bug when holding the hammers in survival mode, Id guess sodium to be the main culprit

Both logs give no information (cryptic, as you said), so it's hard to say what the problem is. Have you tried the game without Sodium? I'll try loading them both up tonight and see if I can reproduce the issue.

If I have a chance tonight ill test it without sodium, if you could do it also thatd be great
