Java Bedrock Skyblock and Bedwars - Items causing lag due to stacking being broken and best moneyfarm in skyblock ruined

[Enteすし。]

So about in december the plugin on cubecraft broke for how they handle items stacking. Items on cubecraft used to stack onto the newest item, whereas vanilla stacks onto the oldest. This causes 2 bigg issues. One for Bedwars and one for Skyblock. On Bedwars items from generators behave weirdly, "stacking" as one item each creating many stacks of just one item that dont stack together with others. Seeing that, its causing lag across the gamemode, as this happens on all teams and generators can be upgrades to insane speeds, causing even more of those 1 item stacks to exist.
Now for the skyblock side: the mechanic of stacking onto the newest item is getting used in the 2 best publicly available moneyfarms for skyblock, as they work by having mobs die on a platform consisting of fence/glasspane in a chesspattern or cobblewalls/lanterns in a chesspattern, in which ofc many items get stuck. However stuck items always got pulled down through the gaps but as of now items stacks on top and pile up until the itemcap gets reached and ot lags the game and server. Before the best rates we had were 270 million per hour, now its likely less than 120 million per hour, a devastating decrease. Unfortunately this bug isnt treated as a bug with the excuse of it "being closer to vanilla", but it is obviously harming players cubecraft experience.

Heres even a video of how INSANE this lag gets within less than 4 minutes of using the farm since the stacking broke.

Update on this for everyone thats reading this:
ive just received news that this issue was not created by a cubecraft plugin breaking, but by a change in paper (a software servers can use for various things such as utility, performance improvements and plugin managment) that made a change to vanilla parity. However as this still poses an issue as mentioned above, it is currently being discussed by devs on how to continue from here on.
(18.3.2026)

Thank you all for making this possible, getting enough people here was very helpful in pushing this issue towards devs attention.

Especially seeing that this design is now used by way more players and is actively promoted on Discord... we need it fixed asap. Players have invested upwards of 2.25B coins to get the maxed capacity 864 pig spawners or 34.5B coins for 864 creepers.

Definitely a "bug" and is affecting QoL for the people that have already invested big $$.

It happened to me too, I hope it can be fixed

It can be fixed quite easily, the question is just whether or not the devs get noticed of this, and finally whether or nit the higherups tell them to fix it as a bug. Orherwise we can just hope for rubik to see this and decide hes gonna squeeze that into his schedule whether or not paid or unpaid

This is really annoying, especially the way it ruins farms, hope itll be fixed!

This needs to be on the top of the thread, why are devs ignoring this?

Were getting this forwarded to them rn, i didnt get a response that it reached them in the bugticket, but i at least know it has been forwarded to the internal tickets by feestja

I could not agree more that this needs to be fixed ASAP.

With how the skyblock economy is, these pig/creeper farms are extremely important to the quality of experience when it comes to the game.

I believe this other bug I have experienced falls within the same ball park, but mobs tend to get stuck in walls and path out of them also.
My wither skeleton farm means that these path out of their trap and one hit you, making experience grinding worthless.

For the issue with item stacking, it is likely that because of the version change some logic regarding item stacking changed. It is very unlikely we will be able to solve the specific change that made this farm not work as well anymore, I tested it and blocks do go through, just not always. I would suggest you find a new farm design. Thank you for your report.
