Bug in function ancestralStateTree, does not write to file

[ferroao]

Function does not write tree to file as expected, it can write to screen or to object. From the updated tutorial from ChromoSSE.Rev (original tutorial was also tested):
psi_anc <- ancestralStateTree(psi, file="out.tree"... ) # does not print to file only to object or screen

Other functions write to file without problem as mnJointConditionalAncestralState

Is there any other function to write a text object (psi_anc) to a text file?
