What I found works for me on building it so it can place easy is. starting by placing an object on 2 opposing corners. You will know you done this because now you will have no reported problems. You can then make any structure you want in the space in the middle. For the corners I like using a stump so it looks like it fits in. Placement is less janky when you use as few materials as possible as there is less issue with collision. But yeah I agree, it’s frustrating to get a bridge working, even harder to make a ramp work. The smallest thing will make it so you can’t cross the bloody thing.
