What it fixes

In modpacks that combine Applied Energistics 2 with certain addons (notably ModularBees — so this hits All The Mods 10), the in-world Jade/WAILA tooltip on AE2 machines (Charger, Inscriber, Energy Cells, ME Controller, etc.) randomly stops showing the Stored: X AE / Y AE energy line and the Device Online/Offline line. Whether it works is decided by a coin-flip every game launch — relogging or resetting Jade config doesn't help.

Why it happens

AE2 registers its tooltip data providers under fixed ids (ae2:power_storage, ae2:grid_node, ae2:debug) for every registered base block-entity class. When an addon registers its own base class, the same ids get registered twice, Jade warns Found different data providers with same id ae2:power_storage, and keeps one of the two at random each launch. Lose the flip → no energy line.

What this mod does

One tiny mixin filters AE2's base-class list down to AE2's own entry, so each provider id is registered exactly once. Deterministic — the tooltip works every launch. No configs, no content, no hardcoded mod names; it compiles against nothing but NeoForge, so it won't break on AE2/addon updates.

Installing

Put it on any client that sees the bug.
Put it on the server too, so the fix survives server restarts (the server rolls the same dice at startup).
It never forces anyone else to install it — clients without it can still join a server with it, and vice versa.

Requires: Minecraft 1.21.1, NeoForge 21.1.x, AE2 19.2+
