Issue: My game crashes when I open a world or it says "Out of Memory".
Solution: Make sure you have more then 1 GB of RAM dedicated to running this modpack (We recommend 4GB to 8GB). This can be done by going to "Launcher Settings" > "Java Settings" > "Memory". If it won't let you select more than 1 GB, you need to install 64-bit Java and change the "Minecraft Java Version" setting to 64-bit.
