I tried the new TFC 0.79.27.903 today but ran into some problems which I've reported here:
http://terrafirmacraft.com/f/topic/9...on-world-load/
The problem is that the game sometimes crashes when loading a world. This happens both in single- and multiplayer. Kittychanley sais she's unable to reproduce the problem. Perhaps it's just me.
Would you guys mind installing the new TFC and see if it works for you? Let me know which launcher you're using.
