So my friend and I finally made it to the Nether in Tekkit and now my client constantly crashes for no reason. Sometimes it says that it has run out of memory (when it really hasn't), and other times there is a message that it just stopped working. The server was working fine before we got to the Nether and the server is being hosted on my laptop wit enough RAM to correctly run the server. My main computer has even more ram (8 GB) and I look in f3 mode when I crash and I never run out of RAM. Any help is welcome.
