Describe the bug
while using the oblivion pickaxe along with ultimite to clear space in the nether, the pickaxe suddendly dissapeared from my inventory, then no block dropped when mined with any other tool

To Reproduce
when the bug occured i was using an oblivion pickaxe enchanted with efficiency 5, unbreaking 3 and mending, mining netherrack while keeping the ultimine key pressed down ine the large tunnel configuration. at the time i was playing with another player via LAN as the host. the other player noticed the blocks they were mining were not dropping.
the problem persisted when exiting the world, but closing minecraft and opening it again fixed it

Minecraft version
minecraft 1.20.1

Mod version
spectrum-1.7.16-deeper-down in Fabric

what

tried to recreate the problem today in a copy of the world

at first i gave myself an oblivion pickaxe with commands, but it broke after only one use.
so i made one in the pedestal and gave myself xp to enchant it with books from my villagers.
went to the nether and started mining using ultimine and the problem ocurred again
as i don't know a lot about programing i can't be sure what is causing the problem, my intuition says it's either the pickaxe or ultimine but if anyone who knows more or can actually understand the logs could clarify it would be apreciated

i pasted the full log of this session here: [https://pastebin.com/Qe15cssT]
the problems occurs at around 11:40, at the end of the log as i closed the world after i recreated the bug

i also managed to record the gameplay when the problem happened and uploaded it here [https://www.youtube.com/watch?v=vf9MGFf6Jpw]

what enchantments do the oblivion pickaxe have, and what do you think they do?

what enchantments do the oblivion pickaxe have, and what do you think they do?

just the normal vanilla enchantments, efficiency 5, unbreaking 3 and mending, plustthe curse of the void that comes with the pick

Rephrased: Do you think a pickaxe that voids drops and Curse of the Void might be related?

have you... watched the linked video? the bug is that after vein mining with the voiding pickaxe, the voiding is STILL APPLYING to other pickaxes

Rephrased: Do you think a pickaxe that voids drops and Curse of the Void might be related?

....yes? that is the reason i posted this here.
i believe you are not understanding what i'm saying or watched the video i posted, i know the oblivion pickaxe voids detroyed items, that is the reason i was using it to clear space in the nether looking for ancient debris, because i din't want all the netherrack, but one the bug ocurred, any block mined with any tool was voided, and not just for me, but also for another players who was connected via lan at the time
