Sorry to re-open/hijack this thread.
I am currently using a iron door style afk fish farm, and am running into an issue. When not running forge, it works fine (the bobber stays in the water, the fishing rod keeps pumping). When I use Forge 1.10.2-12.18.1.2011, the bobber keeps coming back with each pump of the fishing rod, instead of registering in the water and staying. I have tested both vanilla and only forge profiles, so I am certain the issue lies in Forge.
Any thoughts or any info you would like from me?
