I started setting up power transfer in my modpack and accidentally discovered the 'framework view' function that happens when you shift-right click on a routing pipe with an empty hand. However, I also noticed that doing this on some pipes would immediately cause the server to lock up (i.e. Items won't get picked up, interfaces won't open). The client continues fine until it times out. (Or, in the case of single player, you kill java.)

Nothing is written to the console as the server doesn't actually crash; it seems to go into an infinite loop instead.

I've narrowed the modlist down to this:

• Forge 10.13.4.1448
• BuildCraft 7.0.19
• CoFHCore 3.0.3-303
• Logistics Pipes 0.9.2.46
• ThermalExpansion 4.0.3B1-218
• ThermalFoundation 1.2.0-102

A screenshot of the most minimal setup I could make to reproduce the issue

In this setup, shift-right clicking on any of the basic logistics pipes with an empty hand will cause an immediate server freeze.

In the screenshot, the pipes are labeled as such:

• Lapis - Basic Logistics Pipe with a Power Transportation Upgrade
• Emerald - Basic Logistics Pipe with a TE Power Supplier Upgrade
• Iron - Basic Logistics Pipe
• Coal - Unrouted Transport Pipe

Something of note, is if I remove the pipe above the iron block, or replace it with a non-routing pipe, the issue doesn't occur.
