Modpacks: Celestial Journey and Roguelike Adventures and Dungeons
Mod version: JustEnoughIDs 1.0.3-55
Forge version: 14.23.5.2847

Issue: I'm unable to start a modpack with JustEnoughIDs included. I tried version 1.0.3-48 which seems to have issues with Sponge (ArrayOutOfBound issues causing instant disconnects). I wanted to use the latest version of JustEnoughIDs which might solve Sponge compability, but am unable to start it on the client side.

@Xplodin After some more research we figured out that Sponge wasn’t causing the ArrayOutOfBound issue. It is caused by Waterfall (and probably Bungee as well) not allowing bigger packets than vanilla. JEIDS added an update with extended potions which is the cause of that. Removing the server from Waterfall or custom Waterfall version are the best options. Removing the potion update from JeIDS requires clients to have it as well. Having an option to enable or disable this potion update by a modpack developer would fix the issues.

Same error. I cant use spongeforge with R.A.D with justenoughid's installed or uninstalled unless sponge is completely removed.
