Horizons modpack bug

[Davemercer]

Hi, when i try to add Optifine C8 at the pack, crash with this error: 2013-12-08 21:06:08 [INFO] [STDOUT] TConstruct Environment: DO NOT REPORT THIS CRASH! Unsupported mods in environment: optifine

It says it all, Tinkers Construct cannot be installed with OptiFine, remove OptiFine to fix

i cant download the horizon pack at all. what do i need to do?

Wait, the servers are under heavy load, it should let you download in a while, by then there will be a new launcher update too hopefully.

I got heavy amounts of lag even though my computer is a beast w/ 8 GB of ram shouldn't hardcore lag, and then runs out of memory

Is not so simple: i really need optifine, then i've tryed to remove tinker construct and all her add-on, but then there is a problem with metallurgy...
