We have made a large amount of changes to help prevent issues. Increase packet allowance + stacking changes. Should anyone continue to experience issues, please make a new bug report, be as detailed as possible, provide timestamps, and preferably a video if possible. Keep in mind, having an insanely large spawner setup and experiencing chat lag is something we cannot fully prevent, this is a Minecraft client/network limitation, and there's only so much we can do. You will have to adjust your setups and experiment for an optimal experience. @SplayTick @CammyBunny @Imabankthing @SirSpuzzy @Mysticgoli123 @Xdutchless
