Seems to be a known issue with the TDT community (On the FTB forums) that this version of the pack has a broken version of forestry. May we please have a broadcast ingame warning players of this? It does cause a crash to desktop.
Gists of Forestry Crash on TDT The recommended fix is to downgrade forge. I can get the exact version that it would need to be downgraded to if you like. This is going to be fixed in the next update of TDT as per the pack author on the FTB forums.
