I actally almost created this thread almost 12 hours ago before I went to sleep last night. Anyways the issue at hand is greg put code into his mod to crash the client if tinkers construct was installed. This is because TC unnerfed the log into planks that greg introduced recently. As many have pointed out this is configurable but greg decided to toss in an actual crash. According to wyld this code is still there despite greg promising to remove it. And if I am not mistaken this could mean it wont be included in the future feed the beast packs. So that sums it up as I understand. If I forgot something please post it!
