Changelog:

Added the following mods:

• Hourglass

WARNING:

This version of the modpack contains the mods Rubidium and Oculus.
Oculus is used for shaders.
Rubidium is not working properly with Tinkers Construct and causes crashes upon casting something with the smeltery.
If you are not going to use shaders, consider using the 1.2.1a version of this modpack.

Version 1.2.1a is using Embeddium instead of Rubidium but is not capable of using Oculus, so there are no shaders in that version.
