I had an issue earlier in my own testing of when attempting to manually rig any sort of helicotper like in the screenshot when you finish applying the first set of hooks and scroll to get the rope the helicopter jumps away from you (sometimes damaging it as well) and the rope appears to shorten a bit as well, rigging the other ropes works fine after but with the one being shorter it screws up actually trying to pick up the helicopter.

For the jumping, try getting in and out of the heli before you rig it.
You can adjust the length of each individual rope if needed to get an even lift.

I tried that once I thought and it still jumped, but I'll try again. And how do I select which rope I want to adjust?

So testing some things on my own, getting in first can help a little bit but anything larger than a little bird still jumps a little bit, what did seem to help though is how far away I was standing from it when I scrolled to finish placing hooks, closer was better. Also I did notice that when hooking multiple ropes to the same hook, when attaching any additional ropes you have to get a lot closer to the hook in order to see the interaction for it, pretty much have to crawl under the helicopter to get the interaction to attach any additional loads. First attachment normal distance, second or third attachment is about half the interaction distance. And I did figure out how to do the single rope length adjustment, probably should have that in the description, also would be nice in the future to have an option to adjust each manual rig set such as placing two hooks on front of a vehicle and two on back it would be nice to be able to adjust those front and back pairs.

Yeah the closer required distance after first attach is due to ACE interaction line-of-sight stuff. Good point about adding adjustment instructions.

Derp. I've made it public.

If the ropes are not long enough cargo items can end up slingshotting across an area and hurting people if you go too far away from the item after grabbing the ropes.

I assume this is in MP? Are you grabbing the ropes rigged by a different player?

In MP, not placed by anyone else, was the only person on the server to test the mod out a bit.

Hmm. The behaviour should be that you drops the ropes if they get stretched. Are you able to reliably slingshot stuff?

Happened completely randomly, once I remembered to extend the ropes it was fine.

Was this before the update that started matching initial rope length to the size of the cargo?

Is there any way to allow mod vehicles to take sling loads?

I found bug when trying to attach something to helicopter on USS Liberty you can't attach manually hook and when trying to use auto attach thing that I was trying to attach just disappear. PS. I was using your mod with many other mods, so I'm not sure is this bug going to appear with only your mod.
