You can see the log on attached image.

It may seem like a bug of the better barrels mod (jabba), but if I remove it the game crashes again and in the crash log is different mod. It started crashing after I build cobblestone fluid transport pipes and when I removed them with MCEdit it stopped crashing.

(From the log it looks like the renderer for pipes doesn't stop tesselating sometimes.)

don't necrobump old issues, also if you actually read what people say it's an issue with optifine or another mod messing with rendering

Specifically, it's an issue with OptiFine's multi-threaded rendering patches - the rendering pipeline pre-1.8 is not designed to be threaded in this manner, and so some mods (BuildCraft, TCon, ...) will crash with them. Should work fine with said multi-threaded rendering patches disabled or such variants not used, however.

OptiFine is proprietary, so we cannot easily check the specific cause of this issue, and I doubt sp614x would be interested in going all the way back just to help us.

Eh? Strange.

I had 6.4.10 and I tried updating to 6.4.11. Problem was in both. And yes, I have Optifine (version OptiFine_1.7.10_HD_U_B5)

(Minecraft 1.7.10)

What fluid was in the pipe, if any?

There wasn't any. I was just preparing it and it crashed during building.

What BC version are you using?

Do you have Optifine installed?

I blame Optifine

yeah, this is the same bug someone reported on the BCA issuetracker last week, removing optifine fixed it

I'll try it

Solved.
