Clientside Server crash when spongeforge is installed.

[YOYOK9]

I am currently running Server:

• SpongeForge version: 1.12.2-2838.72.2 (was the only version that would boot more or less happily)
• Forge version: 4.23.5.2854
• Java version: 1.8.0_261
• Operating System: Windows Server 2016 Datacenter

Client: Same Forge OS: Windows 10 java: varies per user / crash report.

• Plugins/Mods: Sponge mods: CatClearLag-0.9.5.1 ClearMob-1.12.2-3.0.1 GriefPrevention-1.12.2-4.3.0.692 LuckPerms-Sponge-5.1.17 MagiBridge-API7-2.10.3 Spark (latest) TotalEconomy-1.8.1

Forge Mods: Using mod pack BusinessElite-Plus https://pastebin.com/dZqAZ1Sc

Issue Description Some info: I have already talked with one of the authors from the issue mods and have chalked it up to be a spongeforge issue. Have tried both server side and client. Server is the only one with an issue. We removed sponge from the server and the issue has since stopped.

Issue: The issue is that it seems at random times (was hard to reproduce at it happens at purely random intervals) but the Immersive Engineering mod and its addons seem to be having the same issues with their multiblocks when sponge is on the server. The issue seems to all come back too "Unable to get Y-rotated facing of down". All of these have been strictly clientside crashes and logs/console just says the user has "disconnected"

Reproduction: Install sponge, and the immersive mods, build a few of the multiblocks and wait. It was truely random when it occured. Some took a few irl days, others as soon as the multiblock formed.
