[Bug] In Pattern Provider Multiplication does not work.

[CBEngineer9]

Versions
Minecraft: 1.12.1
Modpack: ATM 10 - 5.4
Mod: 2.1.1

Describe the bug
In pattern provider multiplication button does not work as expected. Clicking the button does seems to multiply the pattern. But changes are lost when closing the pattern provider GUI.

To Reproduce
Steps to reproduce the behavior:

1. Open pattern provider GUI
2. Shift click modify pattern to multiply the pattern by 2
3. Close pattern provider GUI
4. Open pattern provider GUI again to see the patterns are unchanged.
5. See the error log on the server.

Expected behavior
The pattern are multiplied, and persisted even after closing the GUI.

Screenshots

Additional context
I am playing on a dedicated server.

i have come across the exact same thing on my server, i am running the server on my NAS, so i have full access as an admin, first i was very confused, thought i missed something, but tested on singleplayer and there it works as it should, so like it has to be some kind of syncing issue between server and client

[ko-lja]

No it's just a packet being encoded incorrectly by ae2's builtin system, i have a fix in dev

[CinnamonShaey]

Ah I see! Well I was just guessing I am not a developer at all, but good to hear a fix is coming!
