Describe problem (what you were doing / what happened):
Clicked the Storage Request Table with only a Storage Network Master and a few cables attached with export cables to Storage Drawers (mod)

Crash log (if any):

(If this is a suggestion and not a bug report, delete all this and just write your suggestion!)

Note: 1.7.3 does not crash in the same way, so I downgraded.

Old version of fastbench. Yep, going back to 1.7.3 makes sense, thats fine.

In 1.7.4 if you you use it you need a minimum of FastWorkBench 1.7.0

Thanks for the report :)
