What is happening? Interface dont Drop Items when Wrenched and there is No Strorage aviable for the Items How to reproduce? Place interface on Filled Hopper, Configure Interface to Hold items, Wrench The Interface with Network Tool Server or Single Player?: Single Player Screenshot?: No... Crash Log?: No...

Cant reproduce with #97, maybe SS of your setup and configurations before wrenching would help Setup https://imgur.com/a/reDQf GUIs http://puu.sh/8ptEn.png, http://puu.sh/8ptED.png

I can reproduce this with the new version aswell but one difference from your setup is that i have used the Multipart Interface... With the "OLD" Interface its working...

Fixed.
