Quick update on my progress so far:
If you have been following the Live Streams on Tuesdays you will know that a lot of the Tech recipes are now broken
They were working fine on my Client last weekend, but when we loaded them up on the server they all just broke. So I am waiting for the recipes code to get updated. It usually takes a day or two at most so I am not terribly worried about it getting fixed.
Another set back involves issues with NEI, BuildCraft, Forestry and the Questbook. For some reason when I try to update any of these mods I just get fatal errors, so I have not updated any of them in several versions. However I have just discovered that early this month Forestry has added TFC support and I am really interested in trying it out. I do expect that if I try to update Forestry in the current version of the pack it will just break so I think if I start with a fresh instance I might be able to figure out what the compatibility issues are with these 4 mods. Tomorrow I get a whole day off so I am going to give it a try, and hopefully I can have everything ironed out over the weekend and ready to post another version to FTB sometime next week.
I will try to leave a message here on my progress this weekend.
