I TPA'd to hangdown456's base, and instantly crashed to desktop. I've tried restarting my computer. Every time I load minecraft and try to connect to my infinity server, i load into the map and instantly crash to desktop. I get 1 frame of game, and crash. I can't /home out. The actual .txt file dump starts at line 3619. I've posted the entire console dump below from startup to error.
As replied to in your ticket, i have moved you to your base. However someone else will have to take a look at your log. Have a nice day and have fun gaming
All I can see from the logs is that optifine is somehow involved, specifically shaders. Shaders, if not optimized or put on a pc incapable of handling them can easily cause crashes for anyone who goes somewhere super complex. Specifically, Optifine seems to hate sandstone. Turn off connected textures in settings to prevent the sandstone glitch. But from what I can gather from the error stacktrace, it has mentions of Shadersmod, Fastcraft, and a rendering engine (presumably from minecraft). So, my best bet is one of your mods doesn't like his base all that much. I suggest disabling connected textures to prevent future crashes like this one, as Optifine handles connected textures in a rather odd way. TLDR; Turn off connected textures and possibly any shaderpack you have running. It very well might be something with Optifine, as it's common for Optifine not to play nice with other mods when you have connected textures enabled.
We don't normally need console logs, a crash-report is enough. Try disabling fastcraft and give it a whirl again.
