Is there an existing issue for this?

• I did not find any existing issues.

Current Behavior

When some players on my server mine minecraft:spawners (vanilla and modded) the spawner doesn't break and a Ticking Entity exception my occur crashing the server or the spawner may just not break.

Crashlog Ex1: https://pastebin.com/mMKbEQ38 (ad astra lunarian spawner, wouldn't break, crashed server)
Error Log Ex2: https://pastebin.com/EJ0GxFZJ (blaze spawner, wouldn't break)

It may be noted that the crashes occured when Person1 mines any spawner, after installing Neruina mod it would only kick Person1
The error log occured with Person2, they never crashed or were kicked, just couldnt mine the spawner
Person3 had no problems mining spawners

Expected Behavior

EnderIO Broken Spawner drops as normal

Any Additional Information?

No response

I regret to say that we no longer officially support Minecraft 1.20.1 - as such we will not be officially fixing this issue.

If any community member wishes to submit a pull request to address this issue, feel free to open a PR and we will review and merge it.

I will close outstanding 1.20.1 issues in a little while, to keep the issue list clear.

Thanks again for your report.
