I don't know if its the crafting that is crashing it? When I read other posts they include the crash report so here,

Try disabling Placebo's faster recipes

I would, but I've downloaded through twitch and I honestly have no idea how I would remove mods when thats the case.

Bit of an update for you: I played for a good ten minutes without crafting just to see how it runs. It runs perfect, no lag, nothing. I take some birch and put it into logs.... and it crashes as described above. You are probably right about removing faster recipes but I still don't know how to do that.

another update: I figured out how to remove the mod. problem is, other mods broke because of it. Should I delete them too or would that break things worse?

Placebo has a config option to disable their fast recipes, that's what I was suggesting.

Also if you installed twitch recently it puts stuff in C:\Users\You\Twitch (on Windows)

Ah, I see. I'll get on that in the morning than and get back to you to see if it works. Thanks for the help so far!

After a bit of experimentation, it worked! Thanks so much!
