I've tried this several ways to make sure that I've dialed AFTER they moved, and still no luck. I have like four crash logs as a result, but they all seem to be identical beyond the time of the event-- I can include them as well if you have reason to believe they'll have more info, but for now I'll just submit the one.

Admittedly, I've never submitted a mod error before, so I could be doing this completely wrong. If there's something else I need to give you or I need to talk to someone else, just say so.

Just experienced the same crash while attempting to walk to the frame miner. I'm going to tentatively assume the crash is unrelated to the RFtools teleporter and close this.
