I am sorry, "area flowstone" symbol is not yet supported, it is only in
the TODO list :( This is main reason of your problems. OK, I will try to
add it ASAP - it should be relatively easy.
But I expect, that with area flowstone, there is definitely some
orientation needed. Am I correct? This will take some time - there is
some GUI in xtherion needed and we had no oriented area until now.
Regards, S.
