What Version of NeoTech are you using: 1.9 3.0.5

Forge Version: 1858

If possible, did you break and replace the block: Yes

When Shift-right clicking the Iron fluid tank with a neotech wrench, you can dupe the tank instead of picking up the original tank: https://sx.artdude.uk/hotlink-ok/darkosto/H2xA-33fb7-1460097079.png

This same bug seems to occur with all interface pipes too: Screenshot (Same Forge and NeoTech version as above).

This should be fixed in the latest version
