Crashlog If Applicable (Upload to pastebin/gist):

In both FTB Evolution and Opolis Inc, the puller upgrade has randomly stopped working. This is unrelated to loading/unloading, and happens fairly quickly. Using third party item transfer solutions is an effective workaround, so the issue is likely on your end.
