Hello, I know its not the latest version of Forge, but ive never encountered this problem before. So i think it is related to Forge and its chunk loading: This is what happenes in the log: [Shaders] Framebuffer created. [22:23:43] [Client thread/WARN]: Needed to grow BufferBuilder buffer: Old size 1048576 bytes, new size 3145728 bytes. [22:24:17] [Client thread/WARN]: Unable to play unknown soundEvent: minecraft:matmos_interactions.generic_draw [22:26:35] [Client thread/WARN]: Unable to play unknown soundEvent: minecraft:matmos_interactions.generic_draw [22:27:29] [Client thread/INFO]: [Shaders] Framebuffer created. [22:27:29] [Server thread/INFO]: Saving and pausing game... Then it saves, and saves, and more. It lasts about 30 seconds. Ive tried changing version of Forge, but still it happens. I have given Mc 4GB and 512 perm memory. Its for Mc 1.8.9 I use Forge 1722 and ive tried 1738 Im also useing latest Optifine for 1.8.9 H8 Java 1.8.1 131 What could it be? Ps: it might be my perm mem size but im not sure
