With Xorimuth's Power Overload there is a transformer that if ziplined into will result a crash to the main menu.

That's weird, I'll have to try it myself and see. Thanks for letting me know

idk if anything changed but it seems to work just fine for me. I used manual and automatic ziplining and no crash.

Happens on the nearest big pole and pushing up on the transformer. It also sometimes drops me off and sometimes it keeps me on the power line. Likely depending on how the transformer is placed in regards to the pole..

Ok I'm getting the error contently if I'm pressing up and can't move. I'm connecting the wire to the input side.
