I was having the same kind of issue, and since my traps weren’t working properly either, I made a small mod that makes water and lava flows properly push things along as they’re supposed to. If you’d like, give it a try while we wait for an official patch.
By the way, I’ve only tested it in single-player, so I can’t guarantee that it will work properly in multiplayer. Just keep that in mind.
