No saplings dropping in Beta Build 1.2.3-RO.2

I don't know if there is a issue with the beta build but I noticed saplings are not dropping from any trees. The leaves are decaying though. Has anyone else experienced this?

I'm running Beta Build 1.2.3-RO.2 build #2060

 

Have you tried the latest dev build?

 

I just tried the latest dev build 2122. I should at least be seeing 1 sapling per tree, but still they are not dropping. Could a plugin be blocking this? I have multiverse, worldedit, worldguard, and commandbook and a few others that I doubt could be a culprit.

 

I am using that build and I spent a lot of time picking up all saplings that fell from leaves of new-grown jungle-trees (apparently the leaves are to far from the logs)

 

OK I disabled worldguard and saplings are dropping now. I dont see a setting in worldguard that is preventing saplings from falling from trees. Any thoughts on this?
