I'll be working on this tomorrow. For now you can downgrade DynamicTrees, Beta8 was working.

All DynamicTrees versions that i used(BETA10, BETA12 and after your suggestion BETA8) yield the same result for me, however i found that DynamicTrees tree seeds(acorns and such) were not present in the sapling replanting tab.
