Dissapearing Pneumatic Tubes

[DarkDestry]

Im not sure if this is a technical bug or am i plain stupid.

I have a tree farm made using Steve's Carts. The tree farm is connected to a cargo manager which is connected to a cargo distributer. I use a filter/transposer to pull items out of the cargo manager from the cargo distributer. The tubes are connected to 3 barrels each containing the products of the farm.

Here comes the problem. The tubes ontop of the barrels often dissapear on 2 occasions on 2 different servers. REPEATEDLY. It doesnt dissapear when im looking at it and when i came back after i done some things, the tubes dissapear. The chunk are loaded and therefore it should not be entity overload on a single tube. (Not sure if theres a function to explode the pipe on entity overflow but i know BC have one.)

Regardless it have happened MANY times and its getting fustrating. What am i doing wrong ?

This is because pneumatic tubes are counted as a transparent block, and trees, when grown, their leaves will replace any transparent blocks in their way.
I would suggest moving the pneumatic tube system underground to fix this issue.

However in a server, i have the same pipe at the same place with the same setup. When i added more connections to have other stuff flowing through the same pipe line the problem stopped happening
Why ?

It might be because Eloraam put in a safeguard to make sure tubes with items passing through can't be deleted by other blocks. Not sure, though.
