Tested both in modded multyplayer and vanilla. Singleplayer too. There are huge frame issues with this patch things should be tested before releasing them this is not early access anymore. Bug can be expected however cripple the whole experience because with a patch you broke the optimization is no more acceptable in this stage.
Test things before releasing them you will save a lot of time for yourself and also you will avoid people that actually paid for the game to get upset.
Please fix Asap.
